ABSTRACT:
An electrophotographic photosensitive member is formed by disposing a photosensitive layer and a protective layer in this order on a support. The protective layer comprises an applied and cured product of the following solution (A) or (B); (A) a solution comprising a curable resin component and a polymerization initiator having a polymeric recurring structure, or (B) a solution comprising a curable resin component, a polymerization initiator free from a polymeric recurring structure and a polymerization initiator aid having a polymeric recurring structure. Because of the polymerization initiator or polymerization initiator aid having a polymeric recurring structure used for constituting the protective layer, the resultant photosensitive member can exhibit improved durability as well as good electrophotographic performances.
