摘要：
A charge transport layer, which is the surface layer of an electrophotographic photosensitive member, contains a charge transporting material, and a polyester resin A having a repeating structural unit including a specific siloxane moiety and at least one of a polyester resin C having a specific structure and a polycarbonate resin D having a specific structure as a binder resin. The content of the siloxane moiety in the polyester resin A is from 5% by mass or more to 30% by mass or less based on the total mass of the polyester resin A. The charge transport layer includes a domain made of the polyester resin A in a matrix made of the charge transporting material and at least one of the polyester resin C and the polycarbonate resin D.
