Abstract
A heating device includes a planar heater, a heating rotator, a pressure rotator, and one or more charge eliminators. The planar heater includes a base and a resistive heat generator. The heating rotator contacts the heater and includes a conductive layer. The pressure rotator presses the heating rotator and has an outer surface including a conductive material. The one or more charge eliminators contact the conductive layer and the outer surface of the pressure rotator.
