PURPOSE:To reduce abrasion of a photosensitive body at the time of repeated uses and to improve repetition characteristics, such as potential stability by incorporating a copolymer of optionally substituted ethylenic hydrocarbon and (meth)acrylate in the uppermost region on the side of a photosensitive layer. CONSTITUTION:The uppermost regions formed on the side of the photosensitive layer contains the copolymer of the optionally substituted ethylenic hydrocarbon and (meth)acrylate which, when used as a binder together with the polycarbonate, more enhances the mechanical strength characteristic of the polycarbonate, and especially, the impact strength, reduces the abrasion at the time of repeated uses, and improves repetition characteristics, such as potential stability, potential acceptance, and sensitivity. |
