摘要： PROBLEM TO BE SOLVED: To prevent sensitivity from decreasing and remaining electricity from increasing when irradiation with a high energy beam (specially, electron beam) is performed for surface reforming or hardening.
SOLUTION: Of the electrophotographic photoreceptor irradiated with the high energy beam, a binder resin which has a halogen group is incorporated in a photoconductive layer. Thus, the binder resin is incorporated in the photoconductive layer to efficiently prevent deterioration of electrophotographic characteristics arising when the high-energy-beam irradiation is carried out for reforming or forming the surface of the electrophotographic photoreceptor. Further, the electrophotographic photoreceptor can be formed, which has a high-sensitivity and high-function surface layer formed without impairing electrophotographic characteristics.
