PURPOSE:To provide the durability and mechanical durability in terms of electrophotographic characteristics in combination to the electrophotographic body having a photosensitive layer on a conductive base and to obviate the generation of a pause memory effect by incorporating >=1 kinds of lubricant powders, >=1 kinds of specific charge transfer materials and specific compd. into the layer furthest from the substrate of the above-mentioned photosensitive body. CONSTITUTION:This electrophotographic sensitive body has the photosensitive layer on the conductive substrate and the layer furthest from the substrate of said body contains >=1 kinds of the lubricant powders, >=1 kinds of the charge transfer materials having >=0.6V oxidation potential and the compd. expressed by the formula I. The content of the compd. expressed by the formula I is 0.1-30wt.% by the total weight of the charge transfer materials and the binder. The mechanical characteristics such as slipperiness, wear resistance and release property of deposits on the surface layer are effectively improved by the addition of the lubricant powders and the durability to corona products is improved by the use of the charge transfer materials having the high oxidation potential of >=0.6V. Further, the pause memory phenomenon of the photosensitive body is prevented by the compd. of the formula I. |
