Abstract
An image forming apparatus forms a plurality of images of different colors on an intermediate transfer belt by a plurality of image forming portions. The image forming apparatus detects a color misregistration amount of the image formed on the intermediate transfer belt and performs image formation using a correction value based on the color misregistration amount. If an elapsed time from previous image formation is less than a predetermined time, the image forming apparatus predicts the correction value using the previous correction value and the temperature at that time and performs color misregistration correction. If the elapsed time from the previous image formation is a predetermined time or longer, the image forming apparatus predicts the correction value using the correction value and the temperature at the time when the elapsed time becomes a predetermined time or longer and performs the color misregistration correction.
