Abstract
An image forming apparatus is provided in which a misregistration of an image forming-position due to a tension, acting on a continuous recording medium, and a fluctuation thereof, is corrected with a low-cost construction to provide an image of high quality. A pair of recording medium speed detection devices are provided upstream and downstream of an image forming section, respectively, and a misregistration correction amount is calculated from a detected recording medium feed speed so as to correct the image forming position.
