Fixing device having cleaner and temperature detector
To accomplish high-speed fixing which requires high-precision temperature control, or fixing of high-quality color images on various kinds of paper without increasing the size and production cost of the temperature detecting means and contaminating the back sides of paper by toner that comes off from the temperature detecting element, an image forming device is equipped with a fixing device comprising a heating roller, a pressing belt which forcibly contacts the heating roller, and a temperature detecting means which touches the surface of the heating roller to sense the surface temperature of the heating roller, wherein a cleaning means to clean the belt surface is provided on a place which is corresponding to a place at which the contact-type thermistor touches the heating roller.
