る定着装置。 A hollow cylindrical heating roller with a heater lamp inside, a pressure roller that comes into pressure contact with the heating roller, a contact type temperature sensor that detects the surface temperature of the heating roller, and a heating roller that detects the temperature according to the output of the temperature sensor. It is composed of a control unit that controls the energization time of a heater lamp to maintain the surface temperature of the roller at a constant value, and the toner image is removed by passing the printing paper carrying the toner image between the heating roller and the pressure roller. Electrophotographic printing, characterized in that, in a fixing device for fixing an image to printing paper, a contact-type temperature detector for detecting the temperature of the heating roller is disposed outside a paper passage range above the heating roller. Fixing device in the device.
