Abstract
The fixing device of the image forming apparatus of the present invention is provided with a heat transfer probe which contacts the heat roller and a surface temperature of the heat roller is transferred thereto. The erroneous detection of the surface temperature of the heat roller caused from materials adhered to the heat roller is prevented, induction heating coils is regulated at a high level of accuracy using the highly precious detection result obtained from the heat transfer probe, the temperature control of the heat roller is promoted and a fixed image of high quality is obtained.
Claims20
A fixing device of an image forming apparatus comprising:
