Abstract
The fixing device includes a heater, a holding member, a fixing member, a pressure roller, a drive mechanism, and a resistance measuring circuit. The holding member includes a metal portion and holds the heater. The pressure roller is rotatably supported, and applies pressure to a toner image on a sheet by sandwiching the fixing member and the sheet between the pressure roller and the heater. The resistance measuring circuit measures electrical resistance of the metal portion of the holding member. The control device controls whether to allow or prohibit a supply of power to the heater in accordance with a rotation state of the pressure roller and a measured resistance value of the resistance measuring circuit.
