An image forming apparatus includes a plurality of photoreceptors configured to bear respective images, a phase detecting unit configured to perform a phase detection so as to detect respective phases of the plurality of photoreceptors, a phase adjusting unit configured to perform a phase adjustment so as to adjust the respective phases of the plurality of photoreceptors to become in predetermined correlated phase relationships, based on an output from the phase detecting unit, and a control unit configured to specify a first form of an image forming operation in which the phase detecting unit performs the phase detection during a printing operation, and the phase adjusting unit performs the phase adjustment while the plurality of photoreceptors are rotating after a completion of the printing operation so that the plurality of photoreceptors are stopped in the predetermined correlated phase relationships.
