PURPOSE:To obtain a photoreceptor superior in various kinds of potential characteristics in an electrophotographic receptor having a protective layer on a photosensitive layer, by forming an interlayer made of a hardened material contg. a zirconium complex on a photosensitive layer. CONSTITUTION:In an electrophotographic receptor having a photoconductive layer 3 and a surface protective layer 1 on a conductive substrate 4, an interlayer 2 made of a hardened material contg. a zirconium complex and a silane coupling agent is formed between the layers 3, 1, and they are laminated successively to suppress injection of charge from the surface, and to serve as a barrier layer for enhancing electrostatic contrast. As a result, the obtained electrophotographic receptor reduces residual potential and effect of humidity change on charged potential, prevents charge on the surface of the layer 1 from discharging and lowering latent image potential, has various superior potential characteristics, and it can form a defectless image even after long time uses. |
