Electrophotographic photoreceptor, and electrophotographic image forming apparatus and process cartridge using the electrophotographic photoreceptor

摘要

An electrophotographic photoreceptor including an electroconductive substrate; a photosensitive layer overlying the electroconductive substrate optionally via an undercoat layer; and optionally a protective layer overlying the photosensitive layer, wherein an outermost layer of the electrophotographic photoreceptor comprises a binder resin; a particulate fluorine-containing resin in an amount of from 20 to 70% by volume based on total volume of the outermost layer, wherein a surface free energy of the particulate fluorine-containing resin is larger than a surface free energy of the binder resin; and a fluorochemical surfactant in an amount of from 5 to 70% by weight based on total weight of the binder resin.
