Abstract: An image forming apparatus and a control method thereof which execute auto color registration in consideration of mechanical change factors of both photoconductors and drive rollers. The control method of an image forming apparatus includes photoconductors, an intermediate transfer belt to which developers attached to the photoconductors are transferred, and drive rollers to drive the intermediate transfer belt, test patterns are printed on the intermediate transfer belt by adjusting a printing time interval of the test patterns according to a spatial period of the photoconductors and a spatial period of the drive rollers, if conditions to execute auto color registration (ACR) are satisfied, and ACR is executed according to a signal reflected by the test patterns.
