    摘要： This invention relates to an image forming apparatus comprises an image bearing member for bearing a toner image, an intermediate transfer member for allowing the toner image on the image bearing member to undergo electrostatic primary transfer thereto at the position of primary transfer and then enabling the toner image deposited thereon to undergo secondary transfer to a transfer material, and a charging member for charging a residual toner remaining on the intermediate transfer member after the second transfer of the toner image on the intermediate transfer member to a transfer material and consequently causing the residual toner charged by the charging member to be transferred at the position of primary transfer to the image bearing member. Wherein the sum of the surface roughness, Rz, of the intermediate transfer member and that of the charging member is not less than 1 .mu.m and not more than 50 .mu.m.
