Electrophotographic photoreceptor, process cartridge, and image forming apparatus

Abstract

An electrophotographic photoreceptor includes a conductive substrate, a charge generation layer disposed on the conductive substrate, and a charge transport layer disposed on the charge generation layer, in which the charge transport layer contains a phenolic compound, a polyarylate resin, a polycarbonate resin, and a charge transport material, and each of a vector distance DISHT (J/cm3)1/2 between an HSP value of the charge transport material and an HSP value of the polyarylate resin, and a vector distance DISPC (J/cm3)1/2 between the HSP value of the polycarbonate resin and the HSP value of the polyarylate resin, which are calculated based on a Hansen solubility parameter, satisfies Expression (1) and Expression (2), D ⁢ I ⁢ S H ⁢ T ≤ 3.9 , Expression ⁢ ( 1 ) 9.2 ≤ D ⁢ I ⁢ S P ⁢ C < 1 ⁢ 2 . 0 . Expression ⁢ ( 2 )
