摘要： The fixing device of the image forming apparatus of the present invention has a cleaning pad arranged on the upper frame which supports a heat roller. An infrared temperature sensor is supported by a supporting mechanism that is capable of supporting the infrared temperature sensor at the temperature detecting position and the evacuating position. When the right and left frames are attached/removed to/from the main body of the apparatus at the time of maintenance, the infrared temperature sensor is moved to the evacuating position and pressed against the cleaning pad and then, the right and left frames are moved by sliding to the main body of the apparatus. The cleaning pad is also slid and moved jointly with the slide moving of the right and left frames, and the infrared temperature sensor contacts the cleaning pad and dirt on the infrared temperature sensor is removed. As a result of the improvement of temperature detecting accuracy of the infrared temperature sensor, the temperature control of the heat roller is improved and fixed image of high quality is obtained.

摘要： In a fixing device for an image forming apparatus of the invention, circumferences of both side parts of an elastic layer are made larger than a circumference of a central part, and the expansion of a foamed rubber layer is absorbed by space between the elastic layer and a metal conductive layer. Thereby, the hardness of a heat roller at the time of fixing is made nearly uniform across the entire length in the shaft direction. The contact area of a core member and the elastic layer in the both side parts of the heat roller is made larger, and the stress per unit area generated in the elastic layer due to contact with the pressure roller is reduced.
