Abstract
An image forming apparatus includes a plurality of optical scanning devices, a job receiver, a job executor, an image discriminator, a temperature condition judger and a temperature adjuster. When a formation-target image is a single-color image and an image to be formed next is a multi-color image, the temperature adjuster drives a motor of one optical scanning device at a second rotating speed slower than a rotating speed during an image forming operation and drives motors of unused optical scanning devices at a third rotating speed faster than the second rotating speed if a temperature condition is satisfied upon the completion of an image forming operation of the single-color image.
