Abstract:
An intermediate transfer device including an intermediate transfer body having a primary transfer portion and a secondary transfer portion which bears a secondary image formed by transferring a primary image from an image bearing member; a pair of secondary transfer rollers having a secondary transfer roller and a support roller provided in contact with each other via the intermediate transfer body at the secondary transfer portion, which transfers the secondary image to a recording medium at the secondary transfer portion; a variation detection device that detects an amount of variance occurring to a transfer rotation body when the recording medium is transferred to the secondary transfer portion; and an adjustment device that adjusts the distance between the pair of the secondary transfer rollers according to the amount of variance detected by the variation detection device.
