Abstract
An image forming apparatus having: a plurality of image forming sections each of which forms images of respective colors; an intermediate transfer belt; and a control section which executes a color registration correction process and a deviation correction process, wherein the color correction process includes: forming test images on the intermediate transfer belt by the plurality of image forming sections; measuring the test images thereafter; and correcting image forming positions of the image forming sections in response to the measurement results; and wherein the deviation correction process includes: detecting a deviation of the intermediate transfer belt; and correcting the detected deviation, and wherein, when an amount of correction in the deviation correction process exceeds a predetermined level during the execution of the color registration correction process, the control section executes the color registration correction process again.
