Abstract
An electrophotographic image-forming method has a contact charging step of charging the surface of an electrophotographic photosensitive member; an electrostatic latent image forming step of forming an electrostatic latent image on the surface of the electrophotographic photosensitive member charged; a developing step of developing the electrostatic latent image formed into a toner image; and a transfer step of transferring the toner image formed by the development from the electrophotographic photosensitive member to a transfer material, the developing step serving also as a cleaning step for collecting a toner remaining on the electrophotographic photosensitive member after transfer. The toner contains an external additive and the electrophotographic photosensitive member has surface properties of universal hardness of 200 N/mm,or above (provided that a curve that represents the relationship between hardness and depth of indentation by an indenter has no point of inflection) and a coefficient of surface friction of from 0.01 to 1.2.
