Claim:
1. An electrophotographic photosensitive member that abuts with at least any member selected from the group consisting of a charging member that charges the electrophotographic photosensitive member and a developer carrying member that feeds a developer to the electrophotographic photosensitive member, with an abutting member interposed therebetween, wherein the electrophotographic photosensitive member has a first portion and a second portion different from the first portion along the longitudinal direction thereof, and abuts with the abutting member on the second portion, the electrophotographic photosensitive member has a support, a charge generation layer comprising a charge generating material and a polyacetal resin, and a surface layer in this order, the electrophotographic photosensitive member has, in the first portion, an undercoat layer comprising a polymerized product of a composition comprising an electron transporting material and a cross-linking agent, the undercoat layer being adjacent to a surface of the charge generation layer, and the surface facing the support, and the electrophotographic photosensitive member has, in the second portion, an intermediate layer comprising a metal oxide particle and a phenol resin, the intermediate layer being between and adjacent to the support and the charge generation layer.
