    摘要： 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.

    摘要： A toner image formed on a photosensitive drum is transferred on to an intermediate transfer member, and then, from the intermediate member onto a sheet material. The forming width of charge transporting layer of this photosensitive drum (forming width along the longitudinal direction of the photosensitive drum) is longer by more than 4 mm (2 mm each at the both ends) than the width of the intermediate transfer member. As a result, no image blur occurs in the transferred images even when repeating formation of a transferred image onto the intermediate transfer member and formation of the transferred image onto the sheet material.
