Electrophotographic device

Abstract

Abstract PURPOSE:To prevent occurrence of interference fringes on images due to the interference between a reflected light from a conductive base body and a coherent light of the incident light for a long time by setting the roughness and the pitch of ruggedness of the surface of the conductive base body of a photosensitive body within prescribed values by etching. CONSTITUTION:The surface roughness and the pitch of projecting parts of the surface ruggedness of a conductive base body 20 of a photosensitive body 2 are set to 0.05-3.0mum and 0.2-10mum respectively, and a thin film layer 21 consisting of a layer 21A which stops electric charge injection from the base body 20, a layer 21B which receives a laser light to generate carriers, and a protective layer 21C is formed on the base body 20. In case of <=0.05mum roughness and >=0.2mum pitch, interference fringes occur on images because the incident light cannot be scattered sufficiently on the surface of the base body; and in case of >=3mum roughness, 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 when images are formed with the coherent light.
