Abstract:
1. An electrophotographic photosensitive member comprising: a support; a charge-generating layer formed on the support; and a charge-transporting layer formed on the charge-generating layer; wherein the charge-transporting layer is a surface layer of the electrophotographic photosensitive member, and the charge-transporting layer has a matrix-domain structure having: a domain which comprises: a silicone oil having a structural unit represented by the following formula (O-1), and at least one group selected from the group consisting of an alkyl group having 2 to 30 carbon atoms, a polyether group, an aralkyl group, an epoxy group, and an allyl group; and at least one resin selected from the group consisting of: a resin A1 having a structural unit represented by the following formula (A-1) and a structural unit represented by the following formula (B), and a resin A2 having a structural unit represented by the following formula (A-2) and a structural unit represented by the following formula (B); and a matrix which comprises: a resin C having a structural unit represented by the following formula (C); and a charge-transporting substance; wherein a content of the structural unit represented by the formula (A-1) and the structural unit represented by the formula (A-2) is from 10% by mass to 40% by mass based on the total mass of the resin A1 and the resin A2, where, m X Z R n where, m X Z R n where, m X Y R where, m X Y R
