摘要： A fixing apparatus of an image forming apparatus of the present invention strikes a support plate having an infrared temperature sensor against a roller shaft of a heat roller, thereby, regardless of the part accuracy, keeps a gap between the heat roller and the infrared temperature sensor constant. By improvement of the temperature detection accuracy of the infrared temperature sensor, the temperature control of the heat roller is improved and toner images can be fixed always at a fixed temperature. The fixing property is improved and fixed images of high image quality free of ripple marks are obtained.

摘要： A CPU detects a temperature of a central part of a heating roller. If the detected temperature does not exceed 180° C., the CPU drives a central coil or a side-end coil for 0.4 second in accordance with a temperature difference between the central part of the heating roller and a side-end part of the heating roller. Then, the CPU drives the side-end coil or central coil for 0.2 second. Thereafter, the CPU detects the temperature of the central part and repeats the driving control until the detected temperature reaches 180° C.
