Abstract:
An electrophotographic image-forming method comprising 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;said developing step serving also as a cleaning step for collecting a toner remaining on the electrophotographic photosensitive member after transfer;said toner containing an external additive; andsaid electrophotographic photosensitive member having surface properties of universal hardness of 200 N/mm.sup.2 or above, wherein 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.
