Description:
FIELD OF THE INVENTION 
     This invention relates to the improvements in the light receiving member comprising a substrate and a light receiving layer having at least a photoconductive layer formed of an amorphous material containing silicon atom as the main layer constituent and a surface layer. 
     More particularly, it relates to an improved light receiving member suited especially for use in electrophotography which has a light receiving layer having a surface layer formed of an amorphous material containing tetrahedrally bonded boron nitride or both said boron nitride and trihedrally bonded boron nitride being disposed on said photoconductive layer. 
     BACKGROUND OF THE INVENTION 
     For the light receiving members for use in electrophotography and the like, the public attention has been focused on such light receiving members that have a photoconductive layer formed of an amorphous material containing silicon atom as the main layer constituent and hydrogen atom or/and halogen atom [hereinafter referred to as &#34;A--Si(H,X)&#34;]  as disclosed in Unexamined Japanese Patent Publications Sho. 54(1979)-86341 and Sho. 56(1981)-83746, since said photoconductive layer has a high Vickers hardness in addition to having an excellent matching property in the photosensitive region in comparison with that in other kinds of light receiving member and it is not harmful to living things as well as man upon the use. 
     By the way, in any case, such light receiving member comprises a substrate and a photoconductive layer formed of A--Si(H,X). In this respect, it is known to provide a surface layer on the photoconductive layer, which functions to prevent the photoconductive layer from being injected by charges from its free surface side when it is engaged in charging process and to improve the moisture resistance, repeating use characteristics, breakdown voltage resistance, use environmental characteristics and durability of the photoconductive layer, and further in order to make it possible to maintain the quality of the images to be obtained for a long period of time. 
     And there have been made various proposals to form such surface layer using a high resistant and phototransmissive non-monocrystalline material such as amorphous material and polycrystalline material. 
     Among those proposals, there is a proposal to form such surface layer using a boron-nitrogen series amorphous material as disclosed in Unexamined Japanese Patent Publications Sho. 59(1984)12448 and Sho. 60(1985)-61760. 
     However, the boron(B)-nitrogen(N) series amorphous materials to form the foregoing surface layer which are disclosed in said publications are: boron atom and nitrogen atom are contained in unevenly distributed state and in addition, in large amount of hydrogen atom is contained; B--H bond, N--H bond and B--B bond are present in abundance; and the presence of B--N bond is slight and three dimensional structure by B--N bond is little present. 
     Because of this, for the light receiving members disclosed in said publications which has a surface layer formed of said boron-nitrogen series amorphous material, there are still unresolved problems that the surface layer is apt to be easily deteriorated not only with corona discharge in the charging process but also due to various mechanical actions during the contacts with a cleaning blade or other members of the device and as the layer deteriorates, it loses the functions required therefor. In addition to the above problems, the foregoing light receiving member has other problems that it is insufficient in charging efficiency so that it often brings about defective images such as those accompanied with undesired ghosts in the case where it is used in an image-making device. 
     SUMMARY OF THE INVENTION 
     This invention is aimed at eliminating the foregoing problems principally relative to the surface layer in the conventional light receiving member and providing an improved light receiving member having a desirable surface layer which can continuously exhibit the original functions required therefor without accompaniment of the foregoing problems even in repeating use for a long period of time. 
     Another object of this invention is to provide an improved light receiving member for use in electrophotography which always maintains a stable and effective charging efficiency and makes it possible to obtain high quality images even in the case of repeating use for a long period of time. 
     The present inventors have conducted extensive studies for overcoming the foregoing problems on the conventional light receiving members and attaining the objects as described above and, as a result, have accomplished this invention on the findings as below described. 
     That is, the present inventors have experimentally confirmed that the composition of the above mentioned surface layer formed of the foregoing boron-nitrogen series amorphous material is the very factor in order to solve the foregoing problems in the conventional light receiving member. 
     In view of the above, the present inventors have firstly investigated about the situation of influences of various boron nitrides in the cases when they are incorporated into a surface layer of a light receiving member for use in electrophotography. 
     As a result, the findings as below mentioned were obtained and on the basis of those findings, the present inventors have come to the result of acknowledging that not all but only limited kinds of boron nitride are effectively usable as the constituent of said surface layer. 
     That is, one finding is that the hexagonal system boron nitride of which cordination number being 3 is of the same structure as graphite, very soft, and 2 for Mohs hardness, and that in the case where the surface layer is formed of such boron nitride, the resultant light receiving member will become such that is weak against the impacts of active substances such as ion, ozone, electron etc. which will be generated by electric corona and that is apt to be easily deteriorated to lose the functions required therefor when it is mechanically damaged due to contacts with cleaning blade or other members of the electrophotographic copying system. 
     Further, since the hexagonal system boron nitride is of a relatively low electrical resistance, the light receiving member having a surface layer containing such boron nitride is undesirably low for the charging efficiency so that it often bring about defective images as such accompanied with undesired ghosts. 
     Another finding is that the cubic system boron nitride of which cordination number being 4 is of a large Mohs hardness, sufficiently resistant not only against the impacts of the above mentioned active substances but also against mechanical impacts and large enough for electrical resistance, and that in the case where the surface layer is formed of such cubic system boron nitride, the resultant light receiving member will become such desirable one that has a sufficient discharging efficiency and can make high quality images. 
     In view of the above, as far as the strength is concerned, it can be said that the surface layer is desirable to be formed of an amorphous material containing the hexagonal system boron nitride. 
     However, related various factors as below mentioned should be taken into consideration for the preparation of a desirable light receiving member particularly for use in electrophotography. 
     That is, the image-making process using a light receiving member in electrophotographic copying system comprises, typically, corona charging, image exposing, image developing with toner, image transferring to a paper and light receiving member cleaning. In this respect, the surface of the light receiving member will come to contact with plural members respectively of a different quality of the material in each step. 
     Therefore, the quality of an image to be transferred to a paper will largely depend upon whether the contact of the light receiving member with the respective members in the respective steps is suitable or not. For instance, in the case of the cleaning step using a blade, when the surface of the light receiving member is excessively hard, the blade will be worn away at an early stage and as a result, cleaning deficiency is apt to occur. And in that case, since the blade will be short-lived, the maintenance expenses of the copying system eventually become costly. On the other hand, in the case where the surface of the light receiving member is excessively soft, it is easily shaved by the blade to result in bringing about undesirable defects on an image to be made and other than this, the blade will be short-lived. Therefore, the maintenance expenses of the copying system eventually become costly also in this case. 
     In view of the above, it is necessary for the hardness of the surface of the light receiving member to be decided while having due regards on the harmonization thereof with the hardnesses of the respective members with which the light receiving member will contact in the respective steps of the above mentioned image-making process in electrophotographic copying system. Particularly in the case where the surface layer of the light receiving member is tried to form using the foregoing cubic system boron nitride, further appropriate improvements are required in the respective members in the respective steps of the above mentioned image-making process. 
     As a result of further continued studies on the basis of the above findings, the present inventors have come to obtain an acknowledge that either in the case where the surface layer of the light receiving member is made to be such that is formed of a non-monocrystalline material containing at least tetrahedrally bonded boron nitride or both tetrahedrally bonded boron nitride and trihedrally bonded boron nitride in mingled state or in the case where the surface layer is made to be such that is constituted with a lower layer formed of a non-monocrystalline material containing tetrahedrally bonded boron nitride and an upper layer formed of a non-monocrystalline material containing tetrahedrally bonded boron nitride and trihedrally bonded boron nitride in mingled state, the resultant light receiving member having any of the above surface layers becomes to have a desirable harmonization between the hardness of the surface of the light receiving member and the hardnesses of the respective members of the respective steps of the image-making process in electrophotographic copying system. 
     This invention has been completed based on the foregoing various findings, and it typically concerns an improved light receiving member comprising a substrate and a light receiving layer having at least a photoconductive layer formed of an amorphous material containing silicon atom as the main constituent atom and at least one kind atom selected from hydrogen atom and halogen atom and a surface layer, which is characterized in that said surface layer is formed of (1) a non-monocrystalline material containing tetrahedrally bonded boron nitride or (2) a non-monocrystalline material containing tetrahedrally bonded boron nitride and trihedrally bonded boron nitride, or is constituted with a lower layer formed of a non-monocrystalline material containing tetrahedrally bonded boron nitride and an upper layer formed of a non-monocrystalline material containing trihedrally bonded boron nitride in mingled state. 
     And in a preferred embodiment of the improved light receiving member according to this invention, the above mentioned surface layer may further contain dopants, either p-type or n-type. In that case, there is provided a further desirable light receiving member which can exhibit additional functions to prevent accumulation of charges in the surface layer after image exposure and also to further effectively prevent the occurrence of problems relative to image flow and residual voltage. 
     That is, in the case of the conventional light receiving member, the accumulation of charges often occurs in the surface layer after image exposure and the charges accumulated move horizontally near the interface between the surface layer and the photoconductive layer to thereby invite the occurrence of image flow on the resultant image. However, according to the light receiving member having of this invention which has such surface layer containing dopants, either p-type or n-type, charges which are moving into the surface layer after image exposure are mobilized to the free surface of the surface layer so that the occurrence of the problems relative to image flow and also to residual voltage which is often found on the conventional light receiving member can be effectively prevented.

     CONTACT LAYER 106 
     The contact layer 106 in the light receiving member of this invention is to dispose under the photoconductive layer. 
     The main object of disposing the contact layer in the light receiving member of this invention is to enhance the bondability between the substrate and the photoconductive layer, between the charge injection inhibition layer and the photoconductive layer or between the IR absorptive layer and the photoconductive layer. 
     The contact layer 106 is constituted with an A--Si(H,X) material containing at least one kind atom selected from oxygen atom, carbon atom and nitrogen atom [hereinafter referred to as &#34;A--Si(O,C,N) (H,X)&#34;], a poly--Si(H,X) material containing at least one kind atom selected from oxygen atom, carbon atom and nitrogen atom [hereinafter referred to as &#34;poly--Si(O,C,N) (H,X)&#34;] or a Non--Si(H,X) material containing at least one kind atom selected from oxygen atom, carbon atom and nitrogen atom [hereinafter referred to as &#34;Non--Si(O,C,N) (H,X)&#34;]. 
     In the light receiving member of this invention, the amount of nitrogen atoms, oxygen atoms, or carbon atoms to be incorporated in the contact layer is properly determined according to the use purposes. 
     However, the amount of one or more kind atoms of them to be contained in the contact layer is preferrably 1×10 2  to 9×10 5  atomic ppm and more preferrably 1×10 2  tp 4×10 5  atomic ppm. 
     As for the hydrogen atoms(H) and the halogen atoms(X) to be contained in the contact layer, the amount of the hydrogen atoms(H), the amount of the halogen atoms(X) or the sum of the amounts of the hydrogen atoms and the halogen atoms(H+X) is preferably 10 to 7×10 5  atomic ppm, and most preferably, 10 to 2×10 5  atomic ppm in the case where it is constituted with a poly--Si(O,C,N) (H,X) material, and 1×10 3  to 7×10 5  atomic ppm in the case where it is constituted with an A--Si(O,C,N) (H,X) material. 
     And the thickness of the contact layer 106 is preferably 20 Å to 5 μm, more preferably 50 Å to 3 μm, and most preferably, 100 Å to 1 μm. 
     By the way, in the light receiving member of this invention, it is possible to selectively combine the foregoing charge injection inhibition layer 104, IR absorptive layer 105 and contact layer 106. 
     Representative embodiments in that case are shown in FIG. 1(E) to 1(H) and FIGS. 1(E&#39;) to 1(H&#39;). 
     Further, in the light receiving member of this invention, it is possible to make the foregoing charge injection inhibition layer 104 or IR absorptive layer to be such that can function not only as that layer but also as the contact layer. 
     In that case, the object can be attained by incorporating at least one kind atom selected from oxygen atom, carbon atom and nitrogen atom into the corresponding layer. 
     Further in addition, it is also possible to make either the foregoing IR absorptive layer 105 or the foregoing charge injection inhibition layer to be such that can exhibit the functions of the two layers by incorporating the group III element or the group V element into the foregoing IR absorptive layer or by incorporating germanium atom or tin atom into the foregoing charge injection inhibition layer. 
     Now, for the formation of each of the above mentioned constitutent layers, that is, charge injection inhibition layer 104, IR absorptive layer 105 and contact layer 106 of the light receiving member of this invention, any of the known film forming processes such as thermal induced chemical vapor deposition process, plasma chemical vapor deposition process, reactive sputtering process and light induced chemical vapor deposition process can be selectively employed. And among these processes, the plasma chemical vapor deposition process is the most appropriate. 
     For instance, in the case of forming such layer constituted with a poly--Si(H,X) series material by means of plasma chemical vapor deposition (commonly abbreviated to &#34;plasma CVD&#34;), the layer forming operation is practiced while maintaining the substrate at a temperature from 400° to 450° C. in a deposition chamber. 
     In an alternative process, firstly, an amorphous-like film is formed on the substrate being maintained at about 250° C. in a deposition chamber by means of plasma CVD, and secondly the resultant film is annealed by heating the substrate at a temperature of 400° to 450° C. for about 20 minutes or by irradiating laser beam onto the substrate for about 20 minutes to thereby form said layer. 
     PHOTOCONDUCTIVE LAYER 102 
     The photoconductive layer in the light receiving member according to this invention is constituted with an A--Si(H,X) material or a germanium(Ge) or tin(Sn) containing A--Si(H,X) material [hereinafter referred to as &#34;A--Si(Ge,Sn) (H,X)&#34;]. The photoconductive layer 102 may contain the group III element or the group V element respectively having a relevant function to control the conductivity of the photoconductive layer, whereby the photosensitivity of the layer can be improved. 
     As the group III element or the group V element to be incorporated in the photoconductive layer 102, it is possible to use the same element as incorporated into the charge injection inhibition layer 104. It is also possible to use such element having an opposite polarity to that of the element to be incorporated into the charge injection inhibition layer. And, in the case where the element having the same polarity as that of the element to be incorporated into the charge injection inhibition layer is incorporated into the photoconductive layer 102, the amount may be lesser than that to be incorporated into the charge injection inhibition layer. 
     Specifically, the group III element can include B (boron), Al (aluminum), Ga (gallium), In (indium) and Ti (thallium), B and Ga being particularly preferred. The group V element can include, for example, P (phosphor), As (arsenic), Sb (antimony) and Bi (bismuth), P and Sb being particularly preferred. 
     The amount of the group III element or the group V element to be incorporated in the photoconductive layer 102 is preferably 1×10 -3  to 1×10 3  atomic ppm, more preferably, 5×10 -2  to 5×10 2  atomic ppm, and most preferably, 1×10 -1  to 2×10 2  atomic ppm. 
     The halogen atoms(X) to be incorporated in the layer in case where necessary can include fluorine, chlorine, bromine and iodine. And among these halogen atoms, fluorine and chlorine are particularly preferred. The amount of the hydrogen atoms(H), the amount of the halogen atoms(X) or the sum of the amounts for the hydrogen atoms and the haogen atoms(H+X) to be incorporate in the photoconductive layer is preferably 1 to 4×10 atomic %, more preferably, 5 to 3×10 atomic %. 
     Further, in order to improve the quality of the photoconductor layer and to increase it dark resistance, at least one kind atom selected from oxygen atom, carbon atom and nitrogen atom can be incorporated in the photoconductive layer. The amount of these atoms to be incorporated in the photoconductive layer is preferably 1×10 -3  to 50 atomic ppm, more preferably 2×10 -3  to 40 atomic ppm, and, most preferably, 3×10 -3  to 30 atomic ppm. 
     The sensitivity of the photoconductive layer 102 in the light receiving member of this invention against long wavelength light such as laser beam can be further improved by incorporating germanium atom(Ge) or/and tin atom(Sn) thereinto. 
     The amount of the germanium atom or/and the tin atoms in that case is preferred to be in the range of 1 to 9.5×10 5  atomic ppm. 
     The thickness of the photoconductive layer 102 is an important factor in order to effectively attain the object of this invention. The thickness of the photoconductive layer is, therefore, necessary to be carefully determined having due regards so that the resulting light receiving member becomes accompanied with desitred characteristics. 
     In view of the above, the thickness of the photoconductive layer 102 is preferably 3 to 100 μm, more preferably 5 to 80 μm, and most preferably 7 to 50 μm. 
     SURFACE LAYER 103 
     The surface layer 103 in the light receiving member of this invention has a free surface 107 and is disposed on the foregoing photoconductive layer 102. 
     And, the surface layer 103 in the light receiving member of this invention serves not only to improve various characteristics commonly required for a light receiving member such as the humidity resistance, deterioration resistance upon repeating use, breakdown voltage resistance, use-environmental characteristics and durability of the light receiving member but also to effectively prevent electric charges from being injected into the photoconductive layer 102 from the side of fthe free surface 107 at the time when the light receiving layer is engaged in the charging process. 
     The surface layer 103 in the light receiving member of this invention is formed of: (1) a non-monocrystalline material or a polycrystalline material respectively containing tetrahedrally bonded boron nitride [the former will be hereinafter referred to as &#34;Non--BN&#34; or &#34;A--BN&#34; and the latter will be hereinafter referred to as &#34;poly--BN&#34;] or (2) a Non--BN material containing trihedrally bonded boron nitride and tetrahedrally bonded boron nitride in mingled state, or (3) is constituted with a lower constituent layer 103&#39; formed of a Non-BN material containing tetrahdedrally bonded boron nitride and an upper constituent layer 103&#34; containing trihedrally bonded boron nitride and tetrahedrally bonded boron nitride in mingled state.

     The surface layer 103 in the light receiving member of this invention may contain dopants, either p-type or n-type. In this case, the surface layer further effectively serves to mobilize charges which are moving thereinto after the image exposure to its free surface to thereby prevent the occurrence of the problems relative to image flow and also to residual voltage which is often found on the conventional light receiving member. 
     The p-type dopant can include germanium atom(Ge), zinc atom(Zn) and a mixture of them (Ge+Zn). And, the n-type dopant can include silicon atom (Si), tin atom (Sn) or a mixture of them (Si+Sn).

      with respect to y; 
     preferably 0.004≦y≦0.4, more preferably 0.005≦y≦0.3, and most preferably, 0.01≦y≦0.2. 
     The thickness of the surface layer 103 in the light receiving member of this invention is appropriately determined depending upon the desired purpose. 
     It is, however, also necessary that the thickness be determined in view of relative and organic relationship in accordance with the amounts of the constituent atoms to be contained in the layer or the characteristics required in the relationship with the thickness of other layer. Further, it should be determined also in economical viewpoints such as productivity or mass productivity. 
     In view of the above, the thickness of the surface layer 103 is preferably 3×10 -3  to 30 μm, more preferably, 4×10 -3  to 20 μm, and, most preferably, 5×10 -3  to 10 μm. 
     INTERMEDIATE LAYER 108 
     The intermediate layer 108 in the light receiving member of this invention is to dispose between the photoconductive layer 102 and the surface layer 103 and it principally serves to improve breakdown voltage resistance of the light receiving layer. 
     The intermediate layer 108 is formed of either an A--Si(H,X) material or a poly-Si(H,X) material respectively containing carbon atom in an amount of preferably 20 to 90 atomic %, more preferably 30 to 85 atomic %, and most preferably, 40 to 80 atomic %.

     Each layer to constitute the light receiving layer of the light receiving member of this invention can be properly prepared by vacuum deposition method utilizing the discharge phenomena such as glow discharging, reactive sputtering and ion plating processes wherein relevant raw material gases are selectively used. 
     These production methods are properly used selectively depending on the factors such as the manufacturing conditions, the installation cost required, production scale and properties required for the light receiving members to be prepared. The glow discharging method or sputtering method is suitable since the control for the condition upon preparing the light receiving members having desired properties are relatively easy, and hydrogen atoms, halogen atoms and other atoms can be introduced easily together with silicon atoms. The glow discharging method and the sputtering method may be used together in one identical system. 
     FORMATION OF SURFACE LAYER

     The conditions upon forming the surface layer 103 in the light receiving member of this invention, for example, the temperature of the substrate, the gas pressure in the deposition chamber and the electric discharging power are important factors for obtaining an objective surface layer having desired properties and they are properly selected while considering the functions of the layer to be formed. Further, since these layer forming conditions may be varied depending on the kind and the amount of each of the atoms contained in the layer, the conditions have to be determined also taking the kind or the amount of the atoms to be contained into consideration. 
     Specifically, in the case of forming a layer composed of a Non--BN(H,X) material containing tetrahedrally bonded boron nitride by plasma CVD method using high frequency of 13.56 MHz, the gas pressure in the deposition chamber is preferably 10 -2  to 10 Torr, more preferably 5×10 -2  to 2 Torr, and most preferably, 1×10 -1  to 1 Torr.

In this case, the temperature of the substrate and the flow ratios of the gases used are the same as those in the case by plasma CVD method using high frequency. 
     FORMATION OF OTHER LAYERS 
     Basically, when a layer constituted with a--Si(H,X) is formed, for example, by the glow discharging process, gaseous starting material capable of supplying silicon atoms(Si) is introduced together with gaseous starting material for introducing hydrogen atoms(H) and/or halogen atoms(X) into a deposition chamber the inside pressure of which can be reduced, glow discharge is generated in the deposition chamber, and a layer composed of a--Si(H,X) is formed on the surface of a predetermined substrate disposed previously at a predetermined position. 
     The gaseous starting material for supplying Si can include gaseous or gasifiable silicon hydrides (silanes) such as SiH 4 , Si 2  H 6 , Si 4  H 10 , etc., SiH 4  and Si 2  H 6  being particularly preferred in view of the easy layer forming work and the good efficiency for the supply of Si. 
     Further, various halogen compounds can be mentioned as the gaseous starting material for introducing the halogen atoms and gaseous or gasifiable halogen compounds, for example, gaseous halogen, halides, inter-halogen compunds and halogen-substituted silane derivatives are preferred. Specifically, they can include halogen gas such as of fluorine, chlorine, bromine, and iodine; inter-halogen compounds such as BrF, ClF, ClF 3 , BrF 2 , BrF 3 , IF 7 , IC1, IBr, etc.; and silicon halides such as SiF 4 , Si 2  H 6 , SiC 4 , and SiBr 4 . The use of the gaseous or gasifiable silicon halide as described above is particularly advantageous since the layer constituted with halogen atom-containing a--Si can be formed with no additional use of the gaseous starting material for supplying Si. 
     The gaseous starting material usable for supplying hydrogen atoms can include those gaseous or gasifiable materials, for example, hydrogen gas halides such as HF, HCl, HBr, and HI, silicon hydrides such as SiH 4 , Si 2  H 6 , Si 3  H 8 , and Si 4  O 10 , or halogen-substituted silicon hydrides such as SiH 2  F 2 , SiH 2  I 2 , SiH 2  Cl 2 , SiHCl 3 , SiH 2  Br 2 , and SiHBr 3 . The use of these gaseous starting material is advantageous since the content of the hydrogen atoms(H), which are extremely effective in view of the control for the electrical or photoelectronic properties, can be controlled with ease. Then, the use of the hydrogen halide or the halogen-substituted silicon hydride as described above is particularly advantageous since the hydrogen atoms(H) are also introduced together with the introduction of the halogen atoms. 
     In the case of forming a layer comprising a--Si(H,X) by means of the reactive sputtering process or ion plating process, for example, by the sputtering process, the halogen atoms are introduced by introducing gaseous halogen compounds or halogen atom-containing silicon compounds into a deposition chamber thereby forming a plasma atmosphere with the gas. 
     Further, in the case of introducing the hydrogen atoms, the gaseous starting material for introducing the hydrogen atoms, for example, H 2  or gaseous silanes are described above are introduced into the sputtering deposition chamber thereby forming a plasma atmosphere with the gas. 
     For instance, in the case of the reactive sputtering process, a layer comprising a--Si(H,X) is formed on the support by using an Si target and by introducing a halogen atom-introducing gas and H 2  together with an inert gas such as He or Ar as required into a deposition chamber thereby forming a plasma atmosphere and then sputtering the Si target. 
     To form the layer of a--SiGe(H,X) by the glow discharge process, a feed gas to liberate silicon atoms(Si), a feed gas to liberate germanium atoms, and a feed gas to liberate hydrogen atoms(H) and/or halogen atoms(X) are introduced into an evacuatable deposition chamber, in which the glow discharge is generated so that a layer of a--SiGe(H,X) is formed on the properly positioned support. 
     The feed gases to supply silicon atoms, halogen atoms, and hydrogen atoms are the same as those used to form the layer of a--Si(H,X) mentioned above. 
     The feed gas to liberate Ge includes gaseous or gasifiable germanium halides such as GeH 4 , Ge 2  H 6 , Ge 3  H 8 , Ge 4  H 10 , Ge 5  H 12 , Ge 6  H 14 , Ge 7  H 16 , Ge 8  H 18 , and Ge 9  H 20 , with GeH 4 , Ge 2  H 6 , and Ge 3  H 8 , being preferable on account of their ease of handling and the effective liberation of germanium atoms. 
     To form the layer of a--SiGe(H,X) by the sputtering process, two targets (a silicon target and a germanium target) or a single target composed of silicon and germanium is subjected to sputtering in a desired gas atmosphere. 
     To form the layer of a--SiGe(H,X) by the ion-plating process, the vapors of silicon and germanium are allowed to pass through a desired gas plasma atmosphere. The silicon vapor is produced by heating polycrystal silicon or single crystal silicon held in a boat, and the germanium vapor is produced by heating polycrystal germanium or single crystal germanium held in a boat. The heating is accomplished by resistance heating or electron beam method (E.B. method). 
     In either case where the sputtering process or the ion-plating process is employed, the layer may be incorporated with halogen atoms by introducing one of the above-mentioned gaseous halides or halogen-containing silicon compounds into the deposition chamber in which a plasma atmosphere of the gas is produced. In the case where the layer is incorporated with hydrogen atoms, a feed gas to liberate hydrogen is introduced into the deposition chamber in which a plasma atmosphere of the gas is produced. The feed gas may be gaseous hydrogen, silanes, and/or germanium hydrides. The feed gas to liberate halogen atoms includes the above-mentioned halogen-containing silicon compounds. Other examples of the feed gas include hydrogen halides such as HF, HCl, HBr and HI; halogen-substituted silanes such as SiH 2  F 2 , SiH 2  I 2 , SiH 2  Cl 2 , SiHCl 3 , SiH 2  Br 2 , and SiHBr 3  ; germanium hydride halide such as GeHF 3 , GeH 2  F 2 , GeH 3  F, GeHCl 3 , GeH 2  Cl 2 , GeH 3  Cl, GeHBr 3 , GeH 2  Br 2 , GeH 3  Br, GeHI 3 , GeH 2  I 2 , and GeH 3  I; and germanium halides such as GeF 4 , GeCl 4 , GeBr 4 , GeI 4 , GeF 2 , GeCl 2 , GeBr 2 , and GeI 2 . They are in the gaseous form or gasifiable substances. 
     To form the light receiving layer composed of amorphous silicon containing tin atoms (hereinafter referred to as a--SiSn(H,X)) by the glow-discharge process, sputtering process, or ion-plating process, a starting material (feed gas) to release tin atoms(Sn) is used in place of the starting material to release germanium atoms which is used to form the layer composed of a--SiGe(H,X) as mentioned above. The process is properly controlled so that the layer contains a desired amount of tin atoms. 
     Examples of the feed gas to release tin atoms(Sn) include tin hydride(SnH 4 ) and tin halides (such as SnF 2 , SnF 4 , SnCl 2 , SnCl 4 , SnBr 2 , SnBr 4 , SnI 2 , and SnI 4 ) which are in the gaseous form or gasifiable. Tin halides are preferable because they form on the substrate a layer of a--Si containing halogen atoms. Among tin halides, SnCl 4 , is particularly preferable because of its ease of handling and its efficient tin supply. 
     In the case where solid SnCl 4  is used as a starting material to supply tin atoms(Sn), it should preferably be gasified by blowing (bubbling) an inert gas (e.g., Ar and He) into it while heating. The gas thus generated is introduced, at a desired pressure, into the evacuated deposition chamber. 
     The layer may be formed from an amorphous material a--Si(H,X) or a--Si(Ge,Sn)(H,X) which further contains the group III atoms or group V atoms, nitrogen atoms, oxygen atoms, or carbon atoms, by the glow-discharge process, sputtering process, or ion-plating process. In this case, the above-mentioned starting material for a--Si(H,X) or a--Si(Ge,Sn)(H,X) is used in combination with the starting materials to introduce the group III atoms or group V atoms, nitrogen atoms, oxygen atoms, or carbon atoms. The supply of the starting materials should be properly controlled so that the layer contains a desired amount of the necessary atoms. 
     If, for example, the layer is to be formed by the glow-discharge process from a--Si(H,X) containing atoms (O,C,N) or from a--Si(Ge,Sn)(H,X) containing atoms (O,C,N), the starting material to form the layer of a--Si(H,X) or a--Si(Ge,Sn)(H,X) should be combined with the starting material used to introduce atoms (O,C,N). The supply of these starting materials should be properly controlled so that the layer contains a desired amount of the necessary atoms. 
     The starting material to introduce the atoms(O,C,N) may be any gaseous substance or gasifiable substance composed of any of oxygen, carbon, and nitrogen. Examples of the starting materials used to introduce oxygen atoms(O) include oxygen(O 2 ), ozone(O 3 ), nitrogen dioxide(NO 2 ), nitrous oxide(N 2  O), dinitrogen trioxide(N 2  O 3 ), dinitrogen tetroxide(N 2  O 4 ), dinitrogen pentoxide(N 2  O 5 ), and nitrogen trioxide(NO 3 ). Additional examples include lower siloxanes such as disiloxane(H 3  SiOSiH 3 ) and trisiloxane(H 3  SiOSiH 2  OSiH 3 ) which are composed of silicon atoms(Si), oxygen atoms(O), and hydrogen atoms(H). Examples of the starting materials used to introduce carbon atoms include saturated hydrocarbons having 1 to 5 carbon atoms such as methane(CH 4 ), ethane (C 2  H 6 ), propane(C 3  H 8 ), n-butane(n--C 4  H 10 ), and pentane(C 5  H 12 ); ethylenic hydrocarbons having 2 to 5 carbon atoms such as ethylene(C 2  H 4 ), propylene(C 3  H 6 ), butene--1(C 4  H 8 ), butene-2 (C 4  H 8 ), isobutylene(C 4  H 8 ), and pentene(C 5  H 10 ); and acetylenic hydrocarbons having 2 to 4 carbon atoms such as acetylene (C 2  H 2 ), methyl acetylene(C 3  H 4 ), and butine(C 4  H 6 ). Examples of the starting materials used to introduce nitrogen atoms include nitrogen(N 2 ), ammonia(NH 3 ), hydrazine(H 2  NNH 2 ), hydrogen azide(HN 3 ), ammonium azide(NH 4  N 3 ), nitrogen trifluoride(F 3  N), and nitrogen tetrafluoride(F 4  N). 
     In the case of using the glow discharging process for forming the layer or layer region containing oxygen atoms, starting material for introducing the oxygen atoms is added to those selected from the starting materials as desired for forming the light receiving layer. As the starting material for introducing the oxygen atoms, most of those gaseous or gasifiable materials can be used that comprise at least oxygen atoms as the constituent atoms. 
     For instance, it is possible to use a mixture of gaseous starting material comprising silicon atoms(Si) as the constituent atoms, gaseous starting material comprising oxygen atoms(O) as the constituent atom and, as required, gaseous starting material comprising hydrogen atoms(H) and/or halogen atoms(X) as the constituent atoms in a desired mixing ratio, a mixture of gaseous starting material comprising silicon atoms(Si) as the constituent atoms and gaseous starting material comprising oxygen atoms(O) and hydrogen atoms(H) as the constituent atoms in a desired mixing ratio, or a mixture of gaseous starting material comprising silicon atoms(Si) as the constituent atoms and gaseous starting material comprising silicon atoms(Si), oxygen atoms(O) and hydrogen atoms(H) as the constituent atoms. 
     Further, it is also possible to use a mixture of gaseous starting material comprising silicon atoms (Si) and hydrogen atoms (H) as the constituent atoms and gaseous starting material comprising oxygen atoms (O) as the constituent atoms. 
     Specifically, there can be mentioned, for example, oxygen (O 2 ), ozone (O 2 ), nitrogen monoxide (NO), nitrogen dioxide (NO 2 ), dinitrogen oxide (N 2  O), dinitrogen trioxide (N 2  O 3 ), dinitrogen tetraoxide (N 2  O 4 ), dinitrogen pentoxide (N 2  O 5 ), nitrogen trioxide (NO 3 ), lower siloxanes comprising silicon atoms (Si), oxygen atoms (O) and hydrogen atoms (H) as the constituent atoms, for example, disiloxane (H 3  SiOSiH 3 ) and trisiloxane (H 3  SiOSiH 2  OSiH 3 ), etc. 
     In the case of forming the layer or layer region containing oxygen atoms by way of the sputtering process, it may be carried out by sputtering a single crystal or polycrystalline Si wafer or SiO 2  wafer, or a wafer containing Si and SiO 2  in admixture is used as a target and sputtered in various gas atmospheres. 
     For instance, in the case of using the Si wafer as the target, a gaseous starting material for introducing oxygen atoms and, optionally, hydrogen atoms and/or halogen atoms is diluted as required with a dilution gas, introduced into a sputtering deposition chamber, gas plasmas with these gases are formed and the Si wafter is sputtered. 
     Alternatively, sputtering may be carried out in the atmosphere of a dilution gas or in a gas atmosphere containing at least hydrogen atoms (H) and/or halogen atoms (X) as constituent atoms as a sputtering gas by using individually Si and SiO 2  targets or a single Si and SiO 2  mixed target. As the gaseous starting material for introducing the oxygen atoms, the gaseous starting material for introducing the oxygen atoms shown in the examples for the glow discharging process as described above can be used as the effective gas also in the sputtering. 
     The light receiving layer containing carbon atoms, for example, may be formed through the glow discharging process, by using a mixture of gaseous starting material comprising silicon atoms (Si) as the constituent atoms, gaseous starting material comprising carbon atoms (C) as the constituent atoms and, optionally, gaseous starting material comprising hydrogen atoms (H) and/or halogen atoms (X) as the constituent atoms in a desired mixing ratio, a mixture of gaseous starting material comprising silicon atoms (Si) as the constituent atoms and gaseous starting material comprising carbon atoms (C) and hydrogen atoms (H) as the constituent atoms also in a desired mixing ratio, a mixture of gaseous starting material comprising silicon atoms (Si) as the constituent atoms and gaseous starting material comprising silicon atoms (Si), carbon atoms (C) and hydrogen atoms (H) as the constituent atoms, or a mixture of gaseous starting material comprising silicon atoms (Si) and hydrogen atoms (H) as the constituent atoms and gaseous starting material comprising carbon atoms (C) as constituent atoms. 
     Those gaseous starting materials that are effectively usable herein can include gaseous silicon hydrides comprising C and H as the constituent atoms, such as silanes, for example, SiH 4 , Si 2  H 6 , Si 3  H 8  and Si 4  H 10 , as well as those comprising C and H as the constituent atoms, for example, saturated hydrocarbons of 1 to 4 carbon atoms, ethylenic hydrocarbons of 2 to 4 carbon atoms and acetylenic hydrocarbons of 2 to 3 carbon atoms. 
     Specifically, the saturated hydrocarbons can include methane (CH 4 ), ethane (C 2  H 6 ), propane (C 3  H 8 ), n-butane (n--C 4  H 10 ) and pentane (C 5  H 12 ), the ethylenic hydrocarbons can include ethylene (C 2  H 4 ), propylene (C 3  H 6 ), butene-1 (C 4  H 8 ), butene-2 (C 4  H 8 ), isobutylene (C 4  H 8 ) and pentene (C 5  H 10 ) and the acetylenic hydrocarbons can include acetylene (C 2  H 2 ), methylacetylene (C 3  H 4 ) and butine (C 4  H 6 ). 
     The gaseous starting material comprising Si, C and H as the constituent atoms can include silicided alkyls, for example, Si(CH 3 ) 4  and Si(C 2  H 5 ) 4 . In addition to these gaseous starting materials, H 2  can of course be used as the gaseous starting material for introducing H. 
     The layer or layer region constituted with a--SiC(H,X) may be formed through the sputtering process by using a single crystal or polycrystalline Si wafer, a C (graphite) wafer or a wafer containing a mixture of Si and C as a target and sputtering them in a desired gas atmosphere. 
     In the case of using, for example a Si wafer as a target, gaseous starting material for introducing carbon atoms, and hydrogen atoms and/or halogen atoms is introduced while being optionally diluted with a dilution gas such as Ar and He into a sputtering deposition chamber thereby forming gas plasmas with these gases and sputtering the Si wafer. 
     Alternatively, in the case of using Si and C as individual targets or as a single target comprising Si and C in admixture, gaseous starting material for introducing hydrogen atoms and/or halogen atoms as the sputtering gas is optionally diluted with a dilution gas, introduced into a sputtering deposition chamber thereby forming gas plasmas and sputtering is carried out. As the gaseous starting material for introducing each of the atoms used in the sputtering process, those gaseous starting materials used in the glow discharging process as described above may be used as they are. 
     In the case of using the glow discharging process for forming the layer or the layer region containing the nitrogen atoms, starting material for introducing nitrogen atoms is added to the material selected as required from the starting materials for forming the light receiving layer as described above. As the starting material for introducing the nitrogen atoms, most of gaseous or gasifiable materials can be used that comprise at least nitrogen atoms as the constituent atoms. 
     For instance, it is possible to use a mixture of gaseous starting material comprising silicon atoms (Si) as the constituent atoms, gaseous starting material comprising nitrogen atoms (N) as the constituent atoms and, optionally, gaseous starting material comprising hydrogen atoms (H) and/or halogen atoms (X) as the constituent atoms mixed in a desired mixing ratio, or a mixture of starting gaseous material comprising silicon atoms (Si) as the constituent atoms and gaseous starting material comprising nitrogen atoms (N) and hydrogen atoms (H) as the constituent atoms also in a desired mixing ratio. 
     Alternatively, it is also possible to use a mixture of gaseous starting material comprising nitrogen atoms (N) as the constituent atoms gaseous starting material comprising silicon atoms (Si) and hydrogen atoms (H) as the constituent atoms. 
     The starting material that can be used effectively as the gaseous starting material for introducing the nitrogen atoms (N) used upon forming the layer or layer region containing nitrogen atoms can include gaseous or gasifiable nitrogen, nitrides and nitrogen compounds such as azide compounds comprising N as the constituent atoms or N and H as the constituent atoms, for example, nitrogen (N 2 ), ammonia (NH 3 ), hydrazine (H 2  NNH 2 ), hydrogen azide (HN 3 ) and ammonium azide (NH 4  N 3 ). In addition, nitrogen halide compounds such as nitrogen trifluoride (F 3  N) and nitrogen tetrafluoride (F 4  N 2 ) can also be mentioned in that they can also introduce halogen atoms (X) in addition to the introduction of nitrogen atoms (N). 
     The layer or layer region containing the nitrogen atoms may be formed through the sputtering process by using a single crystal or polycrystalline Si wafer or Si 3  N 4  wafer or a wafer containing Si and Si 3  N 4  in admixture as a target and sputtering them in various gas atmospheres. 
     In the case of using a Si wafer as a target, for instance, gaseous starting material for introducing nitrogen atoms and, as required, hydrogen atoms and/or halogen atoms is diluted optionally with a dilution gas, introduced into a sputtering deposition chamber to form gas plasmas with these gases and the Si wafer is sputtered. 
     Alternatively, Si and Si 3  N 4  may be used as individual targets or as a single target comprising Si and Si 3  N 4  in admixture and then sputtered in the atmosphere of a dilution gas or in a gaseous atmosphere containing at least hydrogen atoms (H) and/or halogen atoms (X) as the constituent atoms as for the sputtering gas. As the gaseous starting material for introducing nitrogen atoms, those gaseous starting materials for introducing the nitrogen atoms described previously shown in the example of the glow discharging can be used as the effective gas also in the case of the sputtering. 
     In addition, in the case of forming a layer or layer region constituted with a--Si(H,X) containing the group III or group V atoms by using the glow discharging, sputtering or ion plating process, the starting material for introducing the group III or group V atoms are used together with the starting material for forming a--Si(H,X) upon forming the layer constituted with a--Si(H,X) as described above and they are incorporated while controlling the amount of them into the layer to be formed. 
     Referring specifically to the boron atom introducing materials as the starting material for introducing the group III atoms, they can include boron hydrides such as B 2  H 6 , B 4  H 10 , B 5  H 9 , B 5  H 11 , B 6  H 10 , B 6  H 12  and B 6  H 14  and boron halides such as BF 3 , BCl 3  and BBr 3 . In addition, AlCl 3 , CaCl 3 , Ga(CH 3 ) 2 , InCl 3 , TlCl 3  and the like can also be mentioned. 
     Referring to the starting material for introducing the group V atoms and, specifically to, the phosphor atom introducing materials, they can include, for example, phosphor hydrides such as PH 3  and P 2  H 6  and phosphor halide such as PH 4  I, PF 3 , PF 5 , PCl 3 , PCl 5 , PBr 3 , PBr 5  and PI 3 . In addition, AsH 3 , AsF 5 , AsCl 3 , AsBr 3 , AsF 3 , SbH 3 , SbF 3 , SbF 5 , SbCl 3 , SbCl 5 , BiH 3 , SiCl 3  and BiBr 3  can also be mentioned to as the effective starting material for introducing the group V atoms. 
     In the case of forming the respective constituent layers other than the surface layer of the light receiving layer in the light receiving member of this invention by means of the glow discharging, reactive sputtering or ion plating process, the amount of each of the layer constituent atoms to be contained in a layer to be formed is controlled by appropriately regulating the flow rate of each of the raw material gases and the flow ratio among the raw material gases to be introduced into the deposition chamber. 
     The conditions upon forming each of such layers, for example, the temperature of the substrate, the gas pressure in the deposition chamber and the electrical discharging power are important factors for obtaining a light receiving member having desired properties and they are properly selected while considering the functions of the layer to be formed. Further, since these layer forming conditions may be varied depending on the kind and the amount of each of the atoms contained in the layer, the conditions have to be determined also taking the kind or the amount of the atoms to be contained into consideration. 
     Specifically, in the case of forming a layer composed of an A--Si(H,X) material containing nitrogen atom, oxygen atom, carbon atom, etc., the temperature of the substrate is preferably 50° to 350° C., and more preferably, 50° to 250° C. The gas pressure in the deposition chamber is preferably 0.01 to 1 Torr, and most preferably, 0.1 to 0.5 Torr. And, the electrical discharging power is preferably 0.005 to 50 W/cm 2 , more preferably 0.01 to 30 W/cm 2 , and most preferably, 0.01 to 20 W/cm 2 . 
     And in the case of forming a layer composed of either an A--SiGe(H,X) material or an A--SiGe(M,X) containing the group III atom or the group V atom, the temperature of the substrate is preferably 50° to 350° C., more preferably, 50° to 300° C., and most preferably, 100° to 300° C. The gas pressure in the deposition chamber is preferably 0.01 to 5 Torr, more preferably 0.01 to 3 Torr, and most preferably, 0.01 to 1 Torr. And, the electrical discharging power is preferably 0.005 to 50 W/cm 2 , more preferably 0.01 to 30 W/cm 2 , and most preferably, 0.01 to 20 W/cm 2 . 
     However, the actual conditions for forming the layer such as temperature of the substrate, discharging power and the gas pressure in the deposition chamber can not usually the determined with ease independent of each other. Accordingly, the conditions optimal to the layer formation are desirably determined based on relative and organic relationships for forming the amorphous material layer having desired properties. 
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The invention will be described more specifically while referring to Examples 1 through 312, but the invention is not intended to limit the scope only to these Examples. 
     In each of the Examples, the light receiving layer was formed using the fabrication apparatus shown in FIG. 2 in accordance with the glow discharging process. 
     In the apparatus shown in FIG. 2, gas reservoirs 202, 203, 204, 205, 206, 241 and 247 are charged with raw material gases for forming the respective layers of the light receiving member of this invention, that is, for instance, SiH 4  gas (99.999% purity) in the reservoir 203, B 2  H 6  gas diluted with H 2  gas (99.999% purity, hereinafter referred to as &#34;B 2  H 6  /H 2  gas&#34; in the reservoir 203, NO gas (99.5% purity) in the reservoir 204, B 2  H 6  gas diluted with Ar gas (99.999% purity, hereinafter referred to as &#34;B 2  H 6  /Ar gas&#34;) in the reservoir 205, B 2  H 6  gas diluted with He gas (99.999% purity, hereinafter referred to as &#34;B 2  H 6  /He gas&#34;) in the reservoir 206, SiH 4  gas diluted with He gas (99.999% purity, hereinafter referred to as &#34;SiH 4  /He gas&#34;) in the reservoir 241 and NH 3  gas (99.999% purity) in the reservoir 247. 
     In the case for introducing halogen atoms (X) into a layer, the reservoir for SiH 4  is replaced by another reservoir for SiF 4  gas for instance. 
     Prior to the entrance of these gases into a deposition chamber 201, it is confirmed that valves for the reservoirs 202 through 206, 241 and 247 and a leak valve 235 are closed and that exit valves 217 through 221, 244 and 250, and sub-valves 232 and 233 are opened. Then, a main valve 234 is at first opened to evacuate the inside of the deposition chamber 201 and gas pipings. 
     Then, upon observing that the reading on the vacuum gauge 236 became about 5×10 -6  Torr, the sub-valves 232 and 233 and the exit valves 217 through 221, 244 and 250. 
     Now, reference is made to an example in the case of forming a light receiving layer on an Al cylinder as a substrate 237. 
     SiH 4  gas from the reservoir 202, B 2  H 6  /H 2  gas from the reservoir 203 and NO gas from the reservoir 204 are caused to flow into the mass flow controllers 207, 208 and 209 respectively by opening the valves 222, 223 and 224, controlling the pressure of each of the exit pressure gauges 227, 228 and 229 to 1 kg/cm 2 . Subsequently, the exit valves 217, 218 and 219, and the sub-valve are gradually opened to enter the raw material gases into the deposition chamber 201. In this case, the exit valves 217, 218 and 219 are adjusted so as to a desired value for the ratio among the SiH 4  gas, B 2  H 6  /H 2  gas and the NO gas. 
     The SiH 4  gas flow rate, the B 2  H 6  /H 2  gas flow rate and the NO gas flow rate, and the opening of the main valve 234 is adjusted while observing the reading on the vacuum gauge 236 so as to obtain a desired value for the pressure inside the deposition chamber 201. Then, after confirming that the temperature of the Al cylinder 237&#39; on the substrate holder 237 has been set by a heater 238 within a range from 50° to 350° C., a power source 240 is set to a predetermined electrical power to cause glow discharging in the deposition chamber 201 while controlling the above gas flow rates to thereby form a layer to be the first layer on the Al cylinder 237&#39;. 
     In the above case, it is possible to further improve the film forming speed by using appropriately selected raw material gases. For instance, in the case where Si 2  F 6  gas is used in stead of the SiH 4  gas, the film forming speed will be raised by some holds in comparison with the above case. 
     In order to form a layer to be the second layer on the already formed first layer, closing the exit valves 217 through 221, 244 and 247 opening the subvalves 232 and 233 and entirely opening the main valve 234 to evacuate the inside of the deposition chamber 201 and the gas pipings to be a high vacuum, B 2  H 6  /Ar gas, B 2  H 6  /He gas, NH 3  gas, an appropriate dopant imparting raw material gas and SiH 4  /He gas are fed into the deposition chamber 201 by operating the related valves in the same was as in the case of forming the first layer and the power source 240 is set to a predetermined electric power to cause glow discharging in the deposition chamber while controlling the flow rates of the raw material gases to thereby form the second layer. 
     In the case where the amount of hydrogen atom to be contained in the second layer is desired to be changed, it can be carried out by purposely adding H 2  gas to an appropiate raw material gas and by varying its flow rate as desired. 
     Further, in the case where hydrogen atom is desired to be introduced into the second layer, it can be carried out by feeding NF 3  gas together with an appropiate raw material gas into the deposition chamber 201. 
     All of the exit valves other than those required for upon forming the respective layers are of course closed. Further, upon forming the respective layers, the inside of the system is once evacuated to a high vacuum degree as required by closing the exit valves 217 through 221, 244 and 250 while opening the sub-valves 232 and 233 and fully opening the main valve 234 for avoiding that the gases having been used for forming the previous layer are left in the deposition chamber 201 and in the gas pipeways from the exit valves 217 through 221, 244 and 250 to the inside of the reaction chamber 201. 
     Further, during the film formation process for the respective layers, the substrate 237&#39; is rotated at a predetermined rotation speed by operating motor 239 in order to attain the uniformness fo the layer to be formed.

     In addition, the situation of breakdown voltage for the drum was observed by applying a high direct current voltage onto the drum. 
     Further, in addition, the abrasion resistance of the drum was examined by wearing its surface using a metallic needle having a round top while applying a predetermined load thereon.
