摘要 |
A charge transport layer serving as a surface layer of an electrophotographic photosensitive member contains a charge transporting material, polyester resin A containing a siloxane moiety and at least one of polyester resin C and polycarbonate resin D. The content of a siloxane moiety in polyester resin A is not less than 10% by mass and not more than 40% by mass relative to the total mass of polyester resin A. The charge transport layer has a matrix-domain structure having a matrix formed of the charge transporting material and at least one of polyester resin C and polycarbonate resin D and a domain formed of polyester resin A in the matrix.
