Abstract: The image forming apparatus includes a crimping/release mechanism that switches between a crimping position where a transfer nip is formed and a release position where the intermediate transfer belt and the photosensitive drum are separated from each other, by moving at least one primary transfer section of a plurality of primary transfer sections provided facing a plurality of photosensitive drums respectively, and a processor that performs color misregistration adjustment when a combination of image forming units used for image formation is changed.

Abstract: An image forming apparatus includes the following, a pair of first conveying rollers, a pair of second conveying rollers, a driver which rotates and drives the second conveying rollers by a command value; and a controller which is able to control the driver to perform constant speed control to rotate the pair of second conveying rollers at a constant speed and to perform constant torque control to rotate the pair of second conveying rollers at a constant torque. When the constant torque control is performed, the controller starts the constant torque control with a predetermined initial torque. Based on sheet interval torque detected in a sheet interval term in which the pair of second conveying rollers do not sandwich and convey a sheet after the first sheet reaches the pair of second conveying rollers, the controller corrects the initial torque and calculates a command value for the next sheet.
