Abstract
An image forming apparatus may include one or more photosensitive media, a driving unit to rotate the photosensitive media, a detecting unit to detect a rotational state of each of the photosensitive media and a controller to control the driving unit based on the rotational state detected by the detecting unit so that two adjacent photosensitive media stop with a phase angle difference between them that is capable of compensating for image registration errors.
