Patent ID: 7283768

Claim:
An image forming apparatus comprising a photoreceptor which comprises: a conductive substrate; a subbing layer disposed on the conductive substrate; and a photosensitive layer disposed on the subbing layer; a charging unit for charging a surface of the photoreceptor; an exposure unit for exposing the surface of the photoreceptor to form an electrostatic latent image; a developing unit for developing the electrostatic latent image with a toner to form a toner image; and a transfer unit having an intermediate transfer belt and for primarily transferring the toner image onto the intermediate transfer belt and secondarily transferring a primarily transferred image on the intermediate belt onto a recording medium, wherein the surface of the intermediate transfer belt has a dynamic hardness of from 22×10 9 to 36×10 9 N/m 2 , a dynamic hardness of the surface of the photoreceptor is smaller than the dynamic hardness of the surface of the intermediate transfer belt, the subbing layer has a thickness of 7 μm or more; a layer of the photoreceptor on the farthest side from the conductive substrate contains a fluorine based resin particle; and the surface of the photoreceptor has a dynamic hardness of from 7×10 9 to 13×10 9 N/m 2 .
