Abstract
An image forming apparatus includes an image bearing member, which rotates and bears a toner image, a thickness of the image bearing member having a periodical variation in a rotation direction of the image bearing member, a first image forming device, which forms a toner image on the image bearing member at a first region with a first toner; and a second image forming device, which forms a toner image on the image bearing member at a second region with a second toner. A distance between a central position of the first region in the rotation direction of the image bearing member and a central position of the second region in the rotation direction of the image bearing member is approximately integer multiples of a periodical length in the periodical variation of the thickness of the image bearing member.
