This photosensitive material is superior in mechanical strength and repeat characteristics and has a high glass transition temperature and a high sensitivity.

Description: BACKGROUND OF THE INVENTION The present invention relates to an electrophotosensitive material which is used for image forming apparatus such as copying apparatus, etc. In the image forming apparatus such as copying apparatus, etc., an organic photoconductor (OPC) having a sensitivity within the wavelength range of a light source of the apparatus has exclusively been used. As the organic photoconductor, there have been known a single-layer type electrophotosensitive material having a single photosensitive layer wherein an electric charge generating material and an electric charge transferring material are dispersed in a membrane of a suitable binding resin, and a multi-layer type electrophotosensitive material comprising an electric charge generating layer containing an electric charge generating material and an electric charge transferring layer wherein an electric charge transferring material is dispersed in a membrane of a binding resin, both layers being mutually laminated. Examples of the electric charge generating material include phthalocyanine pigments, bisazo pigments, perylene pigments, etc. Furthermore, examples of the electric charge transferring material include various hole transferring materials such as carbazole compounds, carbazole-hydrazone compounds, oxadiazole compounds, pyrazoline compounds, hydrazone compounds, stilbene compounds, phenylenediamine compounds, benzidine compounds, etc. Furthermore, as the binding resin, a bisphenol A type polycarbonate having excellent mechanical strength has hitherto been used. However, the bisphenol A type polycarbonate is liable to cause gelation because of its high crystallizability and is also insufficient in mechanical strength. Therefore, there has recently been suggested various polycarbonates, e.g. bisphenol C type polycarbonate, bisphenol Z type polycarbonate, bisphenol Z type polycarbonate having a substituent, etc., which are superior to the bisphenol A type polycarbonate in mechanical strength, bisphenol C-copolymer type polycarbonate, etc. as the binding resin of the photoconductor (e.g. Japanese Unexamined Patent Publication Nos. 53-148263 and 1-273046). However, when these novel polycarbonates are used for the formulation of a conventional photoconductor as they are, the mechanical strength of the photoconductor is improved but the sensitivity deteriorates. In addition, the above photoconductor also has a problem that the sensitivity deteriorates considerably when the image is formed repeatedly formed and so-called repeat characteristics are inferior. Furthermore, when the above novel polycarbonates are used, the mechanical strength of the photoconductor is improved but the degree of the improvement is insufficient. Such a photoconductor is also insufficient in durability and heat resistance because of its low glass transition temperature SUMMARY OF THE INVENTION A main object of the present invention is to provide an electrophotosensitive material which is superior in mechanical strength and repeat characteristics and has a high glass transition temperature and a high sensitivity. In order to solve the above problem, the present inventors have studied intensively about electric charge generating materials and hole transferring materials to be used in combination with the polycarbonates mentioned above. As a result, it has been found that, in a single photosensitive layer of the single-layer type photosensitive layer, physical properties of the hole transferring material to be added in large amount (i.e. almost the same amount as that of the polycarbonate in weight ratio) and an affinity between the hole transferring material and polycarbonate have a significant influence on the above respective characteristics. For example, when the affinity between the polycarbonate and hole transferring material is inferior, the hole transferring material is not uniformly dispersed in the photosensitive layer even if the hole transferring material itself is superior in electric charge transferring properties. Therefore, the electric charge transferring properties of the photosensitive layer become insufficient, which results in deterioration of the sensitivity of the photosensitive material. Furthermore, when the electric charge transferring properties of the photosensitive material deteriorate, deterioration of the sensitivity at the time of repeating formation of the image becomes larger as the residual potential increases, which results in deterioration of the repeat characteristics. Furthermore, the mechanical strength of the photosensitive material is maintained by entanglement of main chains of the polycarbonate. When a large amount of the hole transferring material, which is uncongenial to the polycarbonate, is contained in the photosensitive layer, entanglement of main chains is inhibited and the sufficient mechanical strength can not be obtained. Moreover, since a large amount of the hole transferring material is blended as described above, the glass transition temperature of the whole layer becomes low if its melting point is low, which results in deterioration of durability and heat resistance of the photosensitive material. Therefore, the present inventors have studied to find a hole transferring material which is superior in physical properties such as melting point, etc. and is conformable to the polycarbonate mentioned above. As a result, it has been found that six sorts of hole transferring materials, which comprises a benzidine derivative represented by the formula (6): wherein R 1 and R 2 are the same or different and indicate a hydrogen atom or an alkyl group; R 3 , R 4 , R 5 and R 6 are the same or different and indicate an alkyl group or an alkoxy group; and a, b, c and d are the same or different and indicate an integer of 0 to 5; provided that at least one of a, b, c and d indicates an integer of 2 or more, and c and d indicate an integer other than 0 when a and b indicate 0, simultaneously, a benzidine derivative represented by the formula (7): wherein R 7 and R 8 are the same or different and indicate a hydrogen atom or an alkyl group; R 9 and R 10 are the same or different and indicate an alkyl group, an alkoxy group or an aryl group which may have a substituent; R 11 and R 12 are the same or different and indicate an alkyl group or an alkoxy group; and e, f, g and h are the same or different and indicate an integer of 0 to 5, a benzidine derivative represented by the formula (8): wherein R 13 , R 14 , R 15 and R 16 are the same or different and indicate an alkyl group; and R 17 , R 18 , R 19 and R 20 are the same or different and indicate a hydrogen atom, an alkyl group, an alkoxy group or an aryl group which may have a substituent, a benzidine derivative represented by the formula (9): wherein R 21 , R 22 , R 23 and R 24 are the same or different and indicate an alkyl group; and R 25 , R 26 , R 27 and R 28 are the same or different and indicate a hydrogen atom, an alkyl group, an alkoxy group or an aryl group which may have a substituent, an o-phenylenediamine derivative represented by the formula (10): wherein R 29 , R 30 , R 31 and R 32 are the same or different and indicate an alkyl group, an alkoxy group, an aryl group which may have a substituent, or a halogen atom; and q, r, s and t are the same or different and indicate an integer of 1 to 2, and an m-phenylenediamine derivative represented by the formula (11): wherein R 33 , R 34 , R 35 , R 36 and R 37 are the same or different and indicate an alkyl group, an alkoxy group, an aryl group which may have a substituent, a halogen atom, an amino group or a N-substituted amino group; u, v, w and x are the same or different and indicate an integer of 0 to 5; and y indicates an integer of 0 to 4, are suitable for the above conditions, thus the present invention has been accomplished. That is, according to the single-layer electrophotosensitive-material of the present invention, an organic photosensitive layer provided on a conductive substrate contains an electric charge generating material which is at least one material selected from metal-free phthalocyanine pigments and bisazo pigments, an electron transferring material which comprises a diphenoquinone derivative represented by the formula 12: wherein R 37 , R 38 , R 39 and R 40 are the same or different and indicate a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group, at least one sort of the above six sorts of hole transferring materials and at least one of a bisphenol C type polycarbonate of the repeating unit represented by the formula (1): wherein R A and R B are the same or different and indicate a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; R C and R D are the same or different and indicate an alkyl group having 1 to 3 carbon atoms; and R E and R F are the same or different and indicate a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or a halogen atom, a bisphenol Z type polycarbonate, which contains a substituent, of the repeating unit represented by the formula (2): wherein R G and R H are the same or different and indicate an alkyl group having 1 to 3 carbon atoms; and R I and R J are the same or different and indicate a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or a halogen atom, a bisphenol Z type polycarbonate of a repeating unit represented by the formula (3) ,and a bisphenol C-copolymer type polycarbonate of two sorts of repeating units represented by the formula (4): wherein R K and R L are the same or different and indicate a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and R K and R L may bond each other to form a ring; R M and R N are the same or different and indicate an alkyl group having 1 to 3 carbon atoms; and R O and R P are the same or different and indicate a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or a halogen atom and the formula (5): wherein R Q and R R are the same or different and indicate a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or an aryl group which may contain a substituent and R Q and R R may bond each other to form a ring; and R S , R T , R U , R V , R W , R X , R Y and R Z are the same or different and indicate a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or a halogen atom as the binding resin. As described above, the above four sorts of polycarbonates to be used as the binding resin in the electrophotosensitive material of the present invention are superior to a conventional bisphenol A type polycarbonate represented by the formula (A): in mechanical strength. On the other hand, the benzidine derivatives represented by the formulas (6) to (9), o-phenylenediamine derivative represented by the formula (10) and m-phenylenediamine derivative represented by the formula (11) to be used in combination with the above specific polycarbonate are superior in hole transferring properties and conformity, particularly compatibility with the above four sorts of polycarbonates. Therefore, they are uniformly dispersed in the photosensitive layer. In addition, all of the benzidine derivatives represented by the formulas (6) to (9) have a high melting point and, therefore, the glass transition temperature of the organic photosensitive layer can be increased. Furthermore, the o-phenylenediamine derivative represented by the formula (10) and m-phenylenediamine derivative represented by the formula (11) are superior in the above respective characteristics, and further the surface of the organic photosensitive layer is modified by adding any one of them to decrease a friction coefficient and to increase a loss modulus of the whole layer. Therefore, the wear resistance of the organic photosensitive layer can be improved. DETAILED DESCRIPTION OF THE INVENTION In the electrophotosensitive material of the present invention, examples of the alkyl group corresponding to any one of the groups R A to R Z in any one of the repeating units represented by the formulas (1), (2), (4) and (5), which constitutes the polycarbonate as the binding resin, include alkyl groups having 1 to 3 carbon atoms, such as methyl (Me), ethyl (Et), normal propyl (n-Pr), isopropyl (i-Pr), etc. Examples of the halogen atom include chlorine, bromine, fluorine, iodine, etc. In the repeating units represented by the formulas (4) and (5), examples of the ring to be formed by bonding the substituents R K and R L or R Q and R R together with a carbon atom of the main chain to which both substituents are bonded include rings having 3 to 7 carbon atoms, such as a cyclopropane ring, a cyclobutane ring, a cyclopentane ring, a cyclohexane ring, a cycloheptane ring, etc. In the repeating unit represented by the formula (5), examples of the aryl group corresponding to the substituents R Q and R R include a phenyl group, o-terphenyl group, naphthyl group, anthryl group, phenanthryl group, etc. Furthermore, examples of the substituent with which the aryl group is substituted include an alkyl group, alkoxy group, halogen atom, etc. The substituent can be substituted on any position of the aryl group. Examples of the bisphenol C polycarbonate of the repeating unit represented by the formula (1) include those of the repeating units of the following formulas (1-1) to (1-5). Examples of the bisphenol Z type polycarbonate of the repeating unit represented by the formula (2), which has a substituent, include those of the repeating units of the following formulas (2-1) to (2-5). Examples of the bisphenol C-copolymer type polycarbonate comprising two sorts of repeating units represented by the formulas (4) and (5) include a random or block copolymer of the combination of two sorts represented by the following formulas (4,5-1) to (4,5-18). Incidentally, it is preferred that the composition ratio (molar ratio) of the repeating unit represented by the formula (4) to that represented by the formula (5) is within a range of about 9:1 to 3:7. It is preferred that the viscosity-average of the polycarbonates represented by the formulas (1), (2) and (3) and polycarbonate as the copolymer of the formulas (4) and (5) is within a range of about 20,000 to 50,000. When the molecular weight is lower than this range, mechanical characteristics such as wear resistance, etc. are not sufficient. On the other hand, when it exceeds the above range, the polycarbonate can not be dissolved in the solvent, and therefore it becomes difficult to prepare a coating solution for making a photosensitive layer. These specific polycarbonates can be used alone or in combination thereof. In the benzidine derivative represented by any one of the formulas (6) to (9), o-phenylenediamine derivative represented by the formula (10) and m-phenylenediamine derivative represented by the formula (11) to be contained in the organic photosensitive layer as the hole transferring material, together with the above specific polycarbonate, examples of the alkyl group corresponding to any one of the groups R 1 to R 36 include alkyl groups having 1 to 6 carbon atoms, such as normal butyl (n-Bu), isobutyl (i-Bu), secondary butyl (sec-Bu), tertiary butyl (tert-Bu), pentyl, hexyl, etc., in addition to the above alkyl groups having 1 to 3 carbon atoms. Examples of the alkoxy group include alkoxy groups having 1 to 6 carbon atoms, such as a methoxy group, ethoxy group, propoxy group, t-butoxy group, pentyloxy group, hexyloxy group, etc. Examples of the aryl group and halogen group include the same groups as those described above. Examples of the N-substituted amino group corresponding to the substituents R 33 to R 37 in the formula (11) include a methylamino group, dimethylamino group, ethylamino group, diethylamino group, etc. Regarding the benzidine derivative represented by the formula (6) among the above hole transferring materials, two or more groups such as an alkyl group or an alkoxy group are substituted on at least one of outer four phenyl groups. Since the derivative has a high melting point in comparison with a conventional benzidine derivative represented by the formula (B) (see Japanese Patent Publication No. 5-210099), the glass transition temperature of the photosensitive layer can be improved by adding the derivative (6). Furthermore, the above benzidine derivative is superior in conformity, particularly compatibility with the specific polycarbonate. Among them, those in which an alkyl group having three or more carbon atoms is substituted on the phenyl group other than phenyl groups containing two or more substituents among outer four phenyl groups of the benzidine derivative are particularly superior in compatibility with the specific polycarbonate-and are dispersed in the photosensitive layer, more uniformly. Examples of the benzidine derivative represented by the formula (6) include compounds represented by the following formulas (6-1) to (6-5). Regarding the benzidine derivative represented by the formula (7), aryl groups such as a phenyl group may be further substituted on at least two phenyl groups among outer four phenyl groups and the melting point is high in comparison with the conventional benzidine derivative represented by the formula (B) and, therefore, the glass transition temperature of the organic photosensitive layer can be improved by adding it. Furthermore, regarding the above benzidine derivative, spreading of the π electron conjugate system is large in comparison with a conventional one and, therefore, the hole transferring properties are also improved. Furthermore, the above benzidine derivative is superior in conformity, particularly compatibility with the specific polycarbonate and, therefore, it is uniformly dispersed in the photosensitive layer. Examples of the benzidine derivative represented by the formula (7) include compounds represented by the following formulas (7-1) to (7-7). Regarding the benzidine derivative represented by the formula (8), four aryl groups are substituted on biphenyl being a center skeleton and the melting point is high in comparison with the conventional benzidine derivative represented by the formula (B) and, therefore, the glass transition temperature of the organic photosensitive layer can be improved by adding it. Among them, those in which aryl groups such as a phenyl group are substituted on at least one of the four outer phenyl groups have a higher melting point and, therefore, the glass transition temperature of the photosensitive layer can be further improved. Furthermore, the above benzidine derivative is superior in conformity, particularly compatibility with the specific polycarbonate and, therefore, it is uniformly dispersed in the photosensitive layer. Examples of the benzidine derivative represented by the formula (8) include compounds represented by the following formulas (8-1) to (8-4). Regarding the benzidine derivative represented by the formula (9), four alkyl groups are substituted on biphenyl as its center skeleton, similarly, and the melting point is high in comparison with the conventional benzidine derivative represented by the formula (B) and, therefore, the glass transition temperature of the organic photosensitive layer can be improved. Furthermore, since the substitution positions of four alkyl groups are unsymmetrical, the benzidine derivative is superior to the benzidine derivative represented by the formula (8) in conformity, particularly compatibility with the specific polycarbonate and, therefore, it is dispersed in the photosensitive layer more uniformly. Examples of the benzidine derivative represented by the formula (9) include compounds represented by the following formulas (9-1) to (9-4). Regarding the o-phenylenediamine derivative represented by the formula (10) and m-phenylenediamine derivative represented by the formula (11), as described above, the surface of the organic photosensitive layer is modified to decrease the friction coefficient and to increase the loss modulus of the whole layer, by adding it. Therefore, the wear resistance of the organic photosensitive layer can be improved. When two or more substituents or aryl groups such as phenyl groups are substituted on at least one of the four outer phenyl groups of the above both phenylenediamine derivatives (10) and (11), the melting point is high and, therefore, the glass transition temperature of the organic photosensitive layer can be improved. Furthermore, when aryl groups are substituted on any one of outer four phenyl groups, spreading of the π electron conjugate system is large and, therefore, the hole transferring properties are also improved. Furthermore, the above both phenylenediamine derivatives (10) and (11) are superior in conformity, particularly compatibility with the specific polycarbonate, as described above. Among them, those in which the substitution position of the substituent to outer four phenyl groups is not the 3-position but 2-position of the phenyl group, or those in which alkyl groups having 3 or more carbon atoms are substituted on at least one of four phenyl groups are particularly superior in compatibility with the specific polycarbonate. Therefore, they are uniformly dispersed in the photosensitive layer. Examples of the o-phenylenediamine derivative represented by the formula (10) include compounds represented by the following formulas (10-1) to (10-4). Examples of the m-phenylenediamine derivative represented by the formula (11) include compounds represented by the following formulas (11-1) to (11-5). In the electrophotosensitive material of the present invention, the organic photosensitive layer to be formed on the conductive substrate is a single-layer type wherein the hole transferring material, the electric charge generating material and an electron transferring material are contained in the same layer of the above specific polycarbonate to be used as the binding resin. Particularly, the electrophotosensitive material having the single-layer type organic photosensitive layer is suitably used as the positive charging type because of its structure. The electric charge generating material to be used in the present invention includes bisazo pigments and metal-free phthalocyanine pigments. These electric charge generating materials can be used alone or in combination thereof so that the electrophotosensitive material has an absorption wavelength within a desired range. Examples of the electric charge generating material suitable for the organic photosensitive material having a sensitivity within the wavelength range of 700 nm or more, which is used for digital-optical image forming apparatuses using a light source such as semi-conductor laser (e.g. laser beam printer, facsimile, etc.), include X type metal-free phthalocyanine. Since these phthalocyanine pigments are superior in matching with the above hole transferring material, an electrophotosensitive material using both materials in combination has a high sensitivity within the above wavelength range and can be suitably used for digital-optical image forming apparatuses. On the other hand, electric charge generating materials suitable for the organic photosensitive material having a sensitivity within the visible range, which is used for analog-optical image forming apparatus using a white light source such as a halogen lamp (e.g. electrostatic copying machines), preferably include bisazo pigments. Since these bisazo pigments are superior in matching with the above hole transferring material, an electrophotosensitive material using both materials in combination has a high sensitivity within the above wavelength range and can be suitably used for analog-optical image forming apparatus. The diphenoquinone derivative of the material of the invention is superior in not only electron transferring properties but also matching with the above two sorts of electric charge generating materials, six sorts of hole transferring materials and specific polycarbonates. Particularly, it has an action of abstracting electrons from the electric charge generating material in the exposure process of the photosensitive material and, therefore, the electric charge-generating efficiency in the electric charge generating material is improved and the residual potential is decreased. Also, the diphenoquinone derivative causes no carrier trapping which inhibits six sorts of hole transferring materials from transferring electrons. Therefore, it becomes possible to attain higher sensitivity in the single-layer type photosensitive layer wherein both materials are dispersed in the same layer. At the time of exposure, not only electric charge generating material but also hole transferring material are excited to form a singlet excited state having a high reactivity. However, the diphenoquinone derivative has a quenching effect and quenches the excited hole transferring material. Therefore, it inhibits the hole transferring material from deteriorating or decomposing in the single-layer type photosensitive layer, particularly, and improves the stability of the photosensitive material. Examples of the diphenoquinone derivative represented by the formula (12) include compounds represented by the following formulas (12-1) to (12-2). In the electrophotosensitive material of the present invention, the above specific polycarbonates can also be used in combination with various binding resins which have hitherto been used for the organic photosensitive layer. Examples of the other binding resin include thermoplastic resins such as styrene polymers, styrene-butadiene copolymer, styreneacrylonitrile copolymer, styrene-maleic acid copolymer, acrylic copolymer, styrene-acrylic acid copolymer, polyethylene, ethylene-vinyl acetate copolymer, chlorinated polyethylene, polyvinyl chloride, polypropylene, ionomers, vinyl chloride-vinyl acetate copolymer, polyester, alkyd resin, polyamide, polyurethane, polycarbonate other than those described above, polyarylate, polysulfon, diaryl phthalate resin, ketone resin, polyvinyl butyral resin, polyether resin, polyester resin, etc.; crosslinking thermosetting resins such as silicone resin, epoxy resin, phenol resin, urea resin, melamine resin, etc.; photosetting resins such as epoxy acrylate, urethane acrylate, etc. These binding resins can be used alone or in combination thereof. Suitable resins are styrene polymers, acrylic polymers, styrene-acrylic copolymer, polyester, alkyd resin, polycarbonate other than those described above, or polyarylate. Furthermore, in the present invention, there can be used other hole transferring materials which have hitherto been known, together with the above six sorts of hole transferring materials. Examples of the hole transferring material include nitrogen-containing cyclic compounds and condensed polycyclic compounds such as oxadiazole compounds (e.g. 2,5-di(4-methylaminophenyl)-1,3,4-oxadiazole), styryl compounds (e.g. 9-(4-diethylaminostyryl)anthracene), carbazole compounds (e.g. polyvinyl carbazole), diamine compounds other than the above six sorts of diamine compounds, organic polysilane compounds, pyrazoline compounds (e.g. 1-phenyl-3-(p-dimethylaminophenyl)pyrazoline), hydrazone compounds, triphenylamine compounds, indole compounds, oxazole compounds, isoxazole compounds, thiazole compounds, thiadiazole compounds, imidazole compounds, pyrazole compounds, triazole compounds, etc. These hole transferring materials can be used alone or in combination thereof. Furthermore, various additives known to the public, such as deterioration inhibitors (e.g. antioxidants, radical scavengers, singlet quenchers, ultraviolet absorbers, etc.), softeners, plasticizers, surface modifiers, bulking agents, thickening agents, dispersion stabilizers, wax, acceptors, donors, etc. can be formulated in the photosensitive layer without injury to the electrophotographic characteristics. The amount of these additives to be added may be the same as that used in a conventional technique. For example, it is preferred that a steric hindered phenolic antioxidant is formulated in the amount of about 0.1 to 50 parts by weight, based on 100 parts by weight of the binding resin. In order to improve the sensitivity of the photosensitive layer, known sensitizers such as terphenyl, halonaphthoquinones, acenaphthylene may be used in combination with the electric charge generating material. As the conductive substrate to be used for the photosensitive material of the present invention, various materials having a conductivity can be used, and examples thereof include metals such as iron, aluminum, copper, tin, platinum, silver, vanadium, molybdenum, chromium, cadmium, titanium, nickel, palladium, indium, stainless steel, brass, etc.; plastic materials vapor-deposited or laminated with the above metal; glass materials coated with aluminum iodide, tin oxide, indium oxide. The conductive substrate may be made in the form of a sheet or a drum. The substrate itself may have a conductivity or only the surface of the substrate may have a conductivity. It is preferred that the conductive substrate has a sufficient mechanical strength when used. The single-layer type photosensitive material in the present invention is formed by applying a coating solution obtained by dissolving or dispersing a binding resin, an electric charge generating material and a hole transferring material and, if necessary, an electron transferring material in a suitable solvent on a conductive substrate, followed by drying (so-called solution coating method). In the single-layer type photosensitive material, it is preferred that the electric charge generating material may be blended in an amount of 0.5 to 20 parts by weight, particularly 0.5 to 10 parts by weight, based on 100 parts by weight of the binding resin. It is preferred that the hole transferring material may be blended in an amount of 5 to 200 parts by weight, particularly 30 to 150 parts by weight, based on 100 parts by weight of the binding resin. It is preferred that the electron transferring material may be blended in an amount of 5 to 100 parts by weight, particularly 10 to 80 parts by weight, based on 100 parts by weight of the binding resin. When using only one or more of the above four sorts of specific polycarbonates as the binding resin, the proportion of the binding resin is that of the specific polycarbonate itself. When using in combination with the other binding resin, the proportion of the binding resin is the total amount of the specific polycarbonate and other binding resin. Similarly, when using one or more of the above six sorts as the hole transferring material, the proportion of the hole transferring material is that of the six sorts of hole transferring materials. When using in combination with the other hole transferring material, the proportion of the hole transferring material is the total amount of the hole transferring materials. The thickness of the single-layer type photosensitive material is preferably 5 to 50 µm, more preferably 10 to 40 µm. A barrier layer may be formed, in such a range as not to injure the characteristics of the photosensitive material, between the conductive substrate and photosensitive layer. A protective layer may be formed on the surface of the photosensitive layer. When the photosensitive layer is formed by the application method, the electric charge generating material, electric charge transferring material and binding resin may be dispersed and mixed with a suitable solvent using a known method, such as using a roll mill, a ball mill, an atriter, a paint shaker, an ultrasonic dispersion device, etc., and the resulting solution may be applied using a known means, followed by drying. As the solvent for preparing a dispersion solution, there can be used various organic solvents, and examples thereof include alcohols such as methanol, ethanol, isopropanol, butanol, etc.; aliphatic hydrocarbons such as n-hexane, octane, cyclohexane, etc.; aromatic hydrocarbons such as benzene, toluene, xylene, etc.; halogenated hydrocarbons such as dichloromethane, dichloroethane, carbon tetrachloride, chlorobenzene, etc.; ethers such as dimethyl ether, diethyl ether, tetrahydrofuran, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, etc.; ketones such as acetone, methyl ethyl ketone, cyclohexanone, etc.; esters such as ethyl acetate, methyl acetate, etc.; dimethylformaldehyde, dimethylformamide, dimethyl sulfoxide, etc. These solvents may be used alone or in combination thereof. In order to improve a dispersibility of the electric charge transferring material and electric charge generating material as well as a smoothness of the surface of the photosensitive layer, surfactants, leveling agents, etc. may be used. EXAMPLES The following Examples and Comparative Examples further illustrate the present invention in detail.

The single-layer type photosensitive materials of the above respective Examples and Comparative Examples were subjected to the following tests, and their characteristics were evaluated. Photosensitivity test I By using a drum sensitivity tester manufactured by GENTEC Co., a voltage was applied on the surface of the photosensitive material of the respective Examples and Comparative Examples to charge the surface at +700 V. Then, monochromatic light [wavelength: 780 nm (half-width: 20 nm), light intensity: 16 µW/cm 2 ] from white light of a halogen lamp as an exposure light source through a band-pass filter was irradiated on the surface of the photosensitive material (irradiation time: 80 msec.).
