Abstract
A fixing device includes a rotator, a pressure rotator, a heater, a conductor, and a resistor. The rotator includes a conductive layer. The pressure rotator presses the rotator to form a fixing nip between the rotator and the pressure rotator. The heater is in contact with an inner surface of the rotator to heat the rotator. The conductor is in contact with the conductive layer of the rotator and has a resistance value larger than 100 kΩ. The resistor has one end electrically coupled in series to the conductor and another end grounded via an image forming apparatus.
