ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor in which the rise of remaining potential is suppressed and which is therefore superior in durability, and to provide a process cartridge and an electrophotographic device each of which uses the photoreceptor. SOLUTION: The electrophotographic photoreceptor includes: at least a photosensitive layer on an electroconductive support; a surface layer that contains fluororesin particles and a fluorine-based comb graft polymer containing a repeating unit derived from a macromonomer and a repeating unit derived from a monomer having a 1-8C fluoroalkyl group, wherein a phosphorus content of the surface layer is ≤5 ppm, and the process cartridge and the electrophotographic apparatus each using this photoreceptor are also provided.
