PURPOSE:To prevent generation of fogging by interposing a thin layer of a specific alloy between a photosensitive layer consisting of a prescribed material and substrate. CONSTITUTION:A boundary layer 2 which is the thin layer of the selenium- tellurium alloy contg. >=15% tellurium is interposed in the boundary face between the conductive substrate 1 of the electrophotographic sensitive body and an electric charge transfer layer 3 forming the photosensitive layer. Injection of holes from the substrate 1 side is accelerated by this constitution, by which the negative charge potential of the substrate 1 at the time of negative electrostatic charge for the purpose of transfer of a toner having a positive charge is lowered and the fogging in the inter-paper part is weakened. The generation of the fogging is thus substantially prevented and a high-quality image is formed. |
