<P>PROBLEM TO BE SOLVED: To form an image suppressive in color smear, in an image forming apparatus which forms an image by using an intermediate transfer body and a plurality of image forming parts successively arranged along the intermediate transfer body. <P>SOLUTION: The image forming apparatus PR includes the intermediate transfer body 8, and the plurality of image forming parts Y, M, C and K successively arranged along the intermediate transfer body 8. Between the adjacent image forming parts on a more upstream side than the most downstream side image forming part K, a dynamic friction coefficient of a photoreceptor in the downstream side image forming part is equal to or above a dynamic friction coefficient of a photoreceptor in the upstream side image forming part. Between the most downstream side image forming part K and the image forming part C on a more upstream side by one, the dynamic friction coefficient μ(K) of the photoreceptor 1 in the most downstream side image forming part K is larger than a dynamic friction coefficient μ(C) of the photoreceptor in the upstream side image forming part C, that is, [μ(Y)≤μ(M)≤μ(C)<μ(K)] is held. <P>COPYRIGHT: (C)2010,JPO&INPIT |
