PROBLEM TO BE SOLVED: To solve the problem that control is complicated and the stability of actuation is lowered because image forming speed must be switched in the case of switching fixing speed though the fixing speed must be made low in an image forming stage where an image is formed on cardboard, glossy paper and an OHP sheet, and a problem that a device gets larger if the image forming speed is not made low. SOLUTION: The fixing speed is switched and also transfer speed is switched, but the image forming speed is kept constant. |
