Abstract:
1. An image forming apparatus comprising a photoreceptor which comprises: 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 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
