Abstract
An image forming apparatus includes a plurality of optical scanning devices, a mode receiver, a temperature condition judger and a temperature adjuster. In the case of forming an image using one optical scanning device, the temperature adjuster drives motors of unused optical scanning devices at a first rotation speed if a predetermined temperature condition is satisfied and drives the motors of the unused optical scanning devices at a second rotation speed slower than the first rotation speed if image formation is finished during the drive at the first rotation speed.
