Abstract
An image forming apparatus includes: an optical-path deflecting unit that deflects optical paths of optical beams in one group out of two groups, the optical beams being provided in a sub-scanning direction at a predetermined pitch; a scanning unit that scans a surface to in a main scanning direction with the one group of which the optical paths have been deflected and another group of which the optical paths are not deflected; and a control unit that controls the optical-path deflecting unit to deflect optical paths of the optical beams in the one group so that irradiation positions of the optical beams in the one group and irradiation positions of the optical beams in the another group are alternately arranged at regular intervals.
