Abstract:
A fixing device has a heating roller and a pressurizing belt which convey the a recording material in mutual contact while fixing a toner on the recording material, a heater which heats the heating roller, a noncontact first thermister which detects a surface temperature of the heating roller in a position located apart from a surface of the heating roller, a pressurizing unit which is placed inside the pressurizing belt, a second thermister which detects a temperature of the pressurizing unit; and a control section which adjusts the surface temperature of the heating roller by controlling the heater on the basis of a detection temperature of the first thermister and a detection temperature of the second thermister. Thus, fixing device is capable of suppressing a temperature difference generated in noncontact temperature detecting sections and obtaining a stable fixed image performance.
