Abstract
A fixing device capable of suitable fixing even after moving to a print mode by reducing overshoot at moving to a print mode, and an image forming device using this. A mode switching unit informs a set or switched print mode to a calorie control unit and a rotation speed control unit. The calorie control unit controls supply power to a fixing roller, a heating roller and a fixing belt, that is a heating output from a heating means consisting of the fixing roller, the heating roller and the fixing belt according to a print mode informed from the mode switching unit. Therefore, the image fixing temperature of a non-fixed image at the heating means can be maintained at a specified temperature corresponding to a print mode.
