Abstract
The present invention provides a belt fixing device which is aimed at solving problems such as offset, unsteady transportation of recording sheets, and the difficulty in shortening the rise time of a high-speed machine. Such a belt fixing device includes a heating roller, a fixing roller, a fixing belt, and a pressure roller. The heating roller and pressure roller have a heater therein. The fixing pressure in a first fixing process portion is set so low that no wrinkles will appear in a material onto which a toner image is to be fixed. The fixing pressure in a second fixing process portion is set so that desired fixing can be performed.
