<p>PROBLEM TO BE SOLVED: To improve an electrophotographic method composed of at least an electrifying process for uniformly electrifying a photoreceptor, a latent image forming process by light exposure, a development process performing the development of at least one of a white/black image and a color image, a transfer process for transferring a developed developer image and a cleaning process for removing an untransferred residual toner on the photoreceptor in the overall viewpoint. SOLUTION: At least magnetic toner for performing black development and a non-magnetic toner for performing color development are used as developers used in the development process, the average particle diameter of the toner is controlled to be between 4μm and 10μm, an elastic blade is used in the cleaning process and the photoreceptor is formed by laminating successively a photoconductive layer containing amorphous Si and a surface layer on a conductive base body. In the photoreceptor, the surface roughness (Ra) in a square with 10μm side is controlled to be between 15 nm and 40 nm and the average inclination (Δa) in a square with 10μm side is controlled to be between 0.12 and 0.40.</p> |
