PROBLEM TO BE SOLVED: To provide an image forming apparatus which does not cause dislocation of an image or a transfer failure by stabilizing running performance of an intermediate transfer belt, even if load change with respect to movements of the intermediate transfer belt which is caused by a process such as a primary transfer, a secondary transfer or intermediate transfer belt cleaning occurs in the image forming apparatus using the intermediate transfer belt. SOLUTION: The image forming apparatus has an intermediate transfer belt 9 which rotates while being stretched between a driving roller 12 and a tension roller 14, to which a toner image formed on an image carrier is transferred. The driving roller 12 is a primary transfer member and is also a secondary transfer-opposed member arranged at a position opposed to a secondary transfer member 11 via the intermediate transfer belt 9.
