PROBLEM TO BE SOLVED: To provide a charge transport film that suppresses a reduction in mobility thereof due to repeated use.SOLUTION: A charge transport film is formed of a hardened film of a composition including one selected from reactive compounds represented by the general formula (I). The charge transport film is applied to an outermost surface layer (protective layer) of an electrophotographic photoreceptor. In the general formula (I), F represents a charge transport skeleton; D represents a group represented by the general formula (IIa); and m represents an integer of 1 or more and 8 or less. In the general formula (IIa), E represents a group represented by the general formula (IIb); L represents an (n+1)-valent linking group including two or more selected from trivalent or quadrivalent groups derived from an alkylene group, an alkenylene group, -C(=O)-, -N(R)-, -S-, -O-, and alkene or alkane; and n represents an integer of 1 or more and 3 or less. In the general formula (IIb), Rrepresents a halogen atom, an alkyl group, or an alkoxy group; nrepresents an integer of 0 or more and 3 or less; and when nrepresents an integer of 2 or 3, Rmay represent the same group or different group. |
