段を設けたことを特徴とする定着装置。[Claims for Utility Model Registration] A fixing device that heats and fixes toner on a sheet carrying an unfixed toner image onto the sheet using a heating member that is heated by a heat source while being controlled within a predetermined temperature range, In a fixing device equipped with a temperature fuse provided near a heating member to detect temperature and shut off the heat source when the temperature reaches a predetermined temperature, the position of the temperature fuse relative to the heating member is raised to raise the heating member to the predetermined temperature range. The fixing device is characterized in that it is provided with a position variable means that sets the heating member to a first position when the temperature is controlled to be within the predetermined temperature range, and sets the heating member to a second position that is farther from the heating member than the first position when controlling the heating member within the predetermined temperature range. Device.
