Electrophotographic photoreceptor, process cartridge, and image forming apparatus

Abstract

An electrophotographic photoreceptor includes a conductive substrate, a charge generation layer provided on the conductive substrate, a charge transport layer provided on the charge generation layer, and a surface protective layer provided on the charge transport layer, in which the charge transport layer has a film thickness of 8 μm or greater and 25 μm or less, and the surface protective layer is a cured film of a composition, having a film thickness of 10 μm or less and containing a resin (X) that has at least one of a unit represented by Formula (X1) or a unit represented by Formula (X2) and a reactive group-containing charge transport material that contains a reactive group and a charge-transporting skeleton in an identical molecule, in Formula (X1), R101, R102, and R103 each independently represent a hydrogen atom or an alkyl group having 1 or more and 5 or less carbon atoms, L101 represents a single bond, an alkylene group having 1 or more and 5 or less carbon atoms, —O—, —C(═O)—, —C(═O)O—, an aromatic ring that may have a substituent, or a combination thereof, L102 represents a single bond, an alkylene group having 1 or more and 5 or less carbon atoms, —O—, —C(═O)—, —C(═O)O—, or a combination thereof, R104 and R105 each independently represent an alkyl group having 1 or more and 5 or less carbon atoms, n represents an integer of 0 or greater and 300 or less, R106, R107, and R108 each independently represent an alkyl group having 1 or more and 5 or less carbon atoms or —O—[Si(R109)(R110)O]m—Si(R111)(R112)(R113) R109, R110, R111, R112, and R113 each independently represent an alkyl group having 1 or more and 5 or less carbon atoms, and m represents an integer of 0 or greater and 20 or less, in Formula (X2), R201, R202, and R203 each independently represent a hydrogen atom or an alkyl group having 1 or more and 5 or less carbon atoms, L201 represents a single bond, an alkylene group having 1 or more and 5 or less carbon atoms, —O—, —C(═O)—, —C(═O)O—, an aromatic ring that may have a substituent, or a combination thereof, L202 represents a single bond, an alkylene group having 1 or more and 5 or less carbon atoms, —O—, —C(═O)—, —C(═O)O—, or a combination thereof, and R204 is an alkyl group having 6 or more and 30 or less carbon atoms.
