<P>PROBLEM TO BE SOLVED: To reduce a dead space adjacent to a transfer nip part between an intermediate transfer body and a photoreceptor, and to suppress the splashing of toner from the dead space, in an image forming apparatus forming an image by using the intermediate transfer body and a plurality of image forming parts arranged along the intermediate transfer body. Ž<P>SOLUTION: In the plurality of image forming parts Y, M, C and K 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, pressing force of a primary transfer roller 6 in the downstream side image forming part is equal to or above pressing force of the primary transfer roller 6 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 pressing force F(K) of the transfer roller in the most downstream side image forming part K is larger than pressing force F(C) of the transfer roller in the upstream side image forming part C, that is, [F(Y)≤F(M)≤F(C)<F(K)] is held in the image forming apparatus PR.
