Abstract
To provide an image forming apparatus including a first image bearing member, first toner image forming means which forms a first toner image on the first image bearing member, an intermediate transfer member in which a circumferential face is formed, the circumferential face rotates in a predetermined direction by using the center of the circumferential face as a rotating center and the thickness is periodically changed at a predetermined interval in the predetermined rotating direction, a first primary transfer region in which the first toner image on the first image bearing member is transferred to the intermediate transfer member, a second image bearing member and a second primary transfer region in which the toner image on the second image bearing member is transferred to the intermediate transfer member to which the first toner image is transferred, in which the distance between the central position of the first primary transfer region and the central position of the second primary transfer region in the rotating direction of the intermediate transfer member is approximately integer times of the predetermined interval. Thereby, it is possible to restrain misregistration from occurring.
