Abstract: PURPOSE:To prevent occurrence of interference fringes on images due to the interference between a reflected light from a conductive base body and an incident light for a long period by setting the surface roughness and the pitch of ruggedness of the surface of the conductive base body of a photosensitive body within prescribed values be etching. CONSTITUTION:A thin film layer 21 consisting of a layer 21A which stops electric charge injection from a conductive base body 20, a layer 21B which receives a laser light to generate carriers, and a protective layer 21C is formed on the conductive base body 20 having 0.05-3.0mum surface roughness and 0.2-10mum pitch of projecting parts of the surface ruggedness. In case of <=0.05mum roughness and >=10mum pitch, interference fringes are generated on images because the incident light cannot be scattered sufficiently on the surface of the base body; and in case of >=3mum roughness and <=0.2mum pitch, the adhesive strength between the base body and the thin film layer is degraded, and they are peeled partially to degrade the light attenuation characteristic of the surface potential. The roughness of the surface of the base body is set within prescribed values in this manner to prevent the occurrence of interference fringes for a long period when images are formed with a coherent light.

The proportional constants are continuously obtained while the material T is passing the devices 4 and 4', to obtain an almost average constant from these proportional constants. Next, in a case that the material T runs out of the device 4', the meandering quantity is estimated from that time basing on the differences in draft position and rolling load by using the obtained proportional constant.

Due to its shape-memorizing property. The drawn-out master 2 restores its dimensional accuracy by leaving it at a temperature not less than its transition point for several minutes, resulting in allowing to re-use it as the master. Among various types of shape memory resin, which can be used, a trans- polyisoprene-based resin, the transition temperature of which is 50-200 deg.C and the differ ence between molecular mobilities above and below the transition temperature of which is large, is preferably used.
