[PROBLEMS] To provide an electrophotographic photosensitive member that maintains excellent mechanical strength and electrophotographic characteristics. An electrophotographic photosensitive member having a photosensitive layer provided on a conductive substrate and having a surface layer containing a polycarbonate containing a repeating unit represented by the following general formula (1). (Wherein, R is a monovalent hydrocarbon containing no aliphatic unsaturated bond, R 1 is a halogen atom, X and X ′ are alkylene groups having 2 or more carbon atoms, a is an integer of 0 to 4, na is 0 or 1, nb and nc are 1 or 2, provided that na + nb + n c = 3, n1, n2, n3, and n4 are 0 or an integer of 1 or more, provided that n1 + n2 + n3 + n4 = It is an integer of 0 to 450. ) |
