FIXING DEVICE AND FIXING METHOD OF IMAGE FORMING APPARATUS |
摘要 |
In a fixing device of an image forming apparatus of the present invention, inner surfaces of upper and lower frames for respectively supporting a heat roller and a pressure roller are formed as a mirror surface. Between the heat roller and an infrared temperature sensor, an infrared transmission filter for cutting infrared rays beyond a wave length zone equivalent to a heatable area of the heat roller is installed. Detection results of a surface temperature of the heat roller by the infrared temperature sensor are prevented from exceeding the error tolerance due to infrared rays radiated from other than the heat roller. Temperature control for the heat roller is improved and a fixed image of high image quality is obtained.
