    摘要： There are provided a photosensitive member for electrophotography having a good cleaning characteristic when used in combination with a non-magnetic toner and a process speed of 80 mm/sec or larger, and an image forming method and an electrophotographic apparatus using the same. The photosensitive member has an average surface roughness of 0.3 to 5.0 microns and is suitably used in an electrophotographic apparatus including cleaning means comprising an elastomeric blade, and developing means for using a two-component developer which comprises a dry non-magnetic toner comprising a binder resin having a glass transition point of 60.degree. C. or below.

    摘要： An image forming apparatus for forming an over laid image on a transfer material includes an electrophotographic photosensitive member movable along an endless path, a latent image forming device for forming an electrostatic latent image on the photosensitive member, a developing device for developing the electrostatic latent image with toner, and a transfer device for transferring the toner image onto the transfer material. The latent image forming device includes a controller for changing a latent image forming condition go as to reduce a potential difference between a latent image potential formed in a first rotation of the photosensitive drum at the start of image forming operation and a latent image potential in a subsequent rotation, and a latent image to be developed is formed from the first rotation without pre-rotation effected until the charge potential of the photosensitive member is stabilized.

    摘要： 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/mm2 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.
