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 support member that supports a treatment portion in which a heating treatment is performed, a belt that is stretched between at least the heating roller and the support member and that rotates, and 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 the treatment portion including an outer peripheral surface portion of the belt that is supported by the support member and in such a manner as to cause the heating target to pass through the treatment portion. The heating roller is not equipped with a power receiving component configured to receive a rotational power that is transmitted.
