Abstract:
An image forming apparatus comprising:a photosensitive member composed by consecutively laminating at least a photoconductive layer containing amorphous Si and an abraded surface protective layer on an electrically conductive substrate; a charger for charging said photosensitive member; an exposing device for forming an electrostatic latent image on said photosensitive member which is charged; and a developing device for visualizing said electrostatic latent image with a developer, wherein an average inclination &Dgr;a within a range of 10 &mgr;mÃ—10 &mgr;m of the surface of said photosensitive member is within a range of 0.12 to 1.0 by abrading the surface of the photosensitive member, wherein said average inclination &Dgr;a is calculated from three dimensional forms measured with an atomic force microscope, wherein said developer used in said developing device contains a toner and charging acceleration particles having electrical conductivity, and wherein said charger is an electrically conductive elastic contact charging roller comprising a medium resistance layer of rubber or foaming material on a core metal as a flexible member, and the medium resistance layer having a resistance from 1Ã—104 to 1Ã—107 &OHgr;.
