Abstract
A heating device includes a heating roller having a resistance heat-generating layer that generates heat by passage of a current through the resistance heat-generating layer, a pressure rotating body that rotates in such a manner as to press a sheet-shaped heating target that is an object to be subjected to a heating treatment against an outer peripheral surface of the heating roller and in such a manner as to cause the heating target to pass through the outer peripheral surface of the heating roller, and an auxiliary heating unit that supplementarily heats at least an axial end region included in a heat-generating region in which heat is generated by the resistance heat-generating layer of the heating roller.
