PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor, electrophotographic method, electrophotographic device and process cartridge for an electrophotographic device having high resolution, keeping excellent picture quality, causing no fluctuation in the potential even for repeated use and having excellent mechanical and chemical durability when a LD or LED light source for writing having the oscillation wavelength in the range from 400 to 450 nm is used by using an excellent antioxidant and a binder resin which efficiently transmits monochromatic illumination light in 390 to 460 nm wavelength region. SOLUTION: In the electrophotographic photoreceptor having a photosensitive layer directly formed on a conductive supporting body or formed with an intermediate layer interposed, the electrophotographic photoreceptor is irradiated with semiconductor laser light at 400 to 450 nm wavelength as the addressing light, and the photosensitive layer consists of an antioxidant and a binder resin which transmits monochromatic light in 390 to 460 nm wavelength region.
