Abstract
A controller measures a stop duration time when an intermediate transfer belt and a secondary transfer belt are stopped, and based on a measurement result, rotates and stops the intermediate transfer belt such that the stretched position by stretch rollers of the intermediate transfer belt is changed. At the same time, the controller rotates and stops the secondary transfer belt such that a stretched position by stretch rollers of the secondary transfer belt is changed. A time from starting to stopping the rotation of the intermediate transfer belt and a time from starting to stopping the rotation of the secondary transfer belt are overlapped.
