Patent ID: 8364064

Claim:
An intermediate transfer device comprising: an intermediate transfer body comprising a primary transfer portion and a secondary transfer portion which is configured to bear a secondary image formed by transferring a primary image from an image bearing member; a pair of secondary transfer rollers comprising a secondary transfer roller and a support roller provided in contact with each other via the intermediate transfer body at the secondary transfer portion, the pair of secondary transfer rollers being configured to transfer the secondary image to a recording medium at the secondary transfer portion; a variation detection device configured to detect an amount of variance occurring to a transfer rotation body when the recording medium is transferred to the secondary transfer portion, the amount of variance being a speed variation of the transfer rotation body or a variation of a driving current of a motor that drives the transfer rotation body; and an adjustment device configured to adjust a distance between the pair of the secondary transfer rollers according to the amount of variance detected by the variation detection device, the adjustment device including a storage device in which a correction amount for use in adjustment of the distance is stored in at least one table, the at least one table for the correction amount is prepared per preset speed of the one pair of the at least one pair of transfer rotation bodies and is switched according to the speed.
