Abstract
A heating device includes a rotator, a heating source, a reflector, a shield, a rotator holder, and a liquid or semi-solid substance. The rotator is rotatably held. The heating source heats the rotator. The reflector reflects radiant heat emitted from the heating source. The shield is disposed closer to a longitudinal end portion of the rotator than to a longitudinal center portion of the rotator to shield, between the heating source and the rotator, the radiant heat emitted from the heating source. The shield has a reflectance lower than a reflectance of the reflector. The rotator holder holds the longitudinal end portion of the rotator. The liquid or semi-solid substance has lubricity and adheres to the rotator holder.
