Electrophotographic photoreceptor, process cartridge, and image forming apparatus

Abstract

An electrophotographic photoreceptor includes a conductive support, and an undercoat layer, a charge generation layer, and a charge transport layer that are provided in this order on the conductive support, wherein the undercoat layer includes at least metallic oxide particles, a reactive acceptor substance including an anthraquinone structure expressed by the following Formula 1, and a binder resin, the charge generation layer includes hydroxygallium phthalocyanine as a charge generation material, and a reflectance of incident light having a wavelength of 780 nm on a surface of the charge generation layer when the charge transport layer is removed is 17% or greater: wherein the anthraquinone structure expressed by Formula 1 is bonded to another structure at a position of *, and thus forms the reactive acceptor substance, and in Formula 1, n1 represents an integer of 1 to 7.
