    • The present invention provides an electrophotographic photosensitive member, and a process cartridge and an electrophotographic apparatus, each of which has the electrophotographic photosensitive member. In the electrophotographic photosensitive member, a charge transport layer used as a surface layer contains a charge transport material, a polycarbonate resin A which has a specific amount of a specific repeating structural unit of a specific siloxane moiety, and a polyester resin C and/or a polycarbonate resin D, each of which has a specific repeating structural unit. In the charge transport layer, a matrix-domain structure is formed in which a matrix is formed from the charge transport material and the polyester resin C and/or the polycarbonate resin D, and domains are formed in the above matrix from the polycarbonate resin A.
