摘要： An image forming apparatus includes an image forming device for forming an image onto a recording material and a fixing device for fixing the image on the recording material. The fixing device has a rotating member for conveying the recording material, and a controller for controlling the factors related to the peripheral speeds of the rotating member in accordance with the information of the peripheral speeds thereof and the size of the recording material. With the structure thus arranged, it is possible to prevent image problems from taking place due to the difference in the sheet conveying speeds between the image transfer and fixation operations.
