An image forming apparatus detects a plurality of times by changing velocity of a photosensitive drum, color misregistration generated when a developing roller separates from a photosensitive drum and calculates a relation between the velocity of the photosensitive drum and the color misregistration. A velocity of the photosensitive drum is changed and an arbitrary peripheral velocity difference is set between the photosensitive drum and the intermediate transfer belt based on the calculated result.
