Electrophotographic photoreceptor, process cartridge, and image forming apparatus

Abstract

An electrophotographic photoreceptor includes a conductive substrate, and a photosensitive layer disposed on the conductive substrate, in which an outermost surface layer contains a charge transport material, a polyarylate resin having a dicarboxylic acid unit represented by Formula (A) and a diol unit represented by Formula (B), a polycarbonate resin, and a phenolic compound having 3 or fewer phenolic functional groups and a molecular weight of 300 or more, and a value of a dielectric loss tangent tan δ of the outermost surface layer at a frequency of 1 Hz is 0.50 or less, in Formula (A), ArA1 and ArA2 are each independently an aromatic ring which may have a substituent, LA is a single bond or a divalent linking group, and nA1 is 0, 1, or 2, in Formula (B), ArB1 and ArB2 are each independently an aromatic ring which may have a substituent, LB is a single bond, an oxygen atom, a sulfur atom, or —C(Rb1)(Rb2)—, and nB1 is 0, 1, or 2, where Rb1 and Rb2 are each independently a hydrogen atom, an alkyl group having 1 or more and 20 or less carbon atoms, an aryl group having 6 or more and 12 or less carbon atoms, or an aralkyl group having 7 or more and 20 or less carbon atoms, and Rb1 and Rb2 may be bonded to each other to form a cyclic alkyl group.
