PROBLEM TO BE SOLVED: To prevent scuffing due to a cleaning blade and a developer, to suppress the reduction of surface film thickness and to improve the durability of a photoreceptor by specifying the difference between the coeffts. of static friction and kinematic friction of the surface of the top layer of the photosensitive layer. SOLUTION: In this electrophotographic photoreceptor with a photosensitive layer on the electrically conductive substrate, the difference between the coeffts. (μS) and (μK) of static friction and kinematic friction of the surface of the top layer of the photosensitive layer is <=0.03. In this case, the photosensitive layer is disposed on the electrically conductive substrate and a substrate of a metallic material such as Al, stainless steel, Cu or Ni, a polyester film or an insulating substrate of paper, etc., with an electrically conductive layer of Al, Cu, Pd, tin oxide, indium oxide, etc., on the surface is used as the electrically conductive substrate. A known barrier layer used in general may be interposed between the electrically conductive substrate and the photosensitive layer.
