The image forming apparatus is capable of preventing operation noise of a drive part from increasing in performing phase adjustment of an image bearing member, reducing consumption power, or achieving a reduction in motor specifications. Based on a rotation phase of a photosensitive drum (1K) detected by a phase detection sensor and a rotation phase of another photosensitive drum detected by a phase detection sensor, a CPU performs the phase adjustment by reducing a rotation speed of a motor (C) that is driving the another photosensitive drum so as to achieve a predetermined phase relationship, and causes an image forming unit to form an image after the phase adjustment is finished.
