PURPOSE:To enhance reflectance and to obtain surface smoothness by forming a specified conductive layer composed essentially of a conductive white pigment and a binder resin between a substrate and a photosensitive layer to prepare an electrophotographic sensitive body. CONSTITUTION:The conductive layer having a reflectance of >=90% and a resistivity of <=10<12>OMEGA.cm, and composed essentially of a conductive white pigment and a binder resin is formed between a substrate and a photosensitive layer to prepare an electrophotographic sensitive body. The following requirements are enumerated as the coating material to be used for said conductive layer: (1) high light reflectance, (2) capability of forming a smooth surface, (3) low resistance and no accumulation of static electricity, (4) not adversely affecting electrophotographic characteristics, (5) sufficient adhesion to the substrate, and (6) sufficient resistance to solvents in the coating material to be used for the photosensitive layer, etc. The binder resin is used in an amt. of 20-50wt%, thus permitting reflectance to be enhanced, surface smoothness to be obtained, and a thick coating film to be obtained. |
