A heating device includes a rotator, a heating source, a reflector, a rotator holder, and a liquid or semi-solid substance. The rotator is rotatably held. The heating source heats the rotator. The reflector includes a reflection face that reflects radiant heat emitted from the heating source. The reflection face has a reflectance lower at each end portion of the reflection face in a longitudinal direction of the rotator than at a center portion of the reflection face in the longitudinal direction of the rotator. The rotator holder holds a longitudinal end portion of the rotator. The liquid or semi-solid substance has lubricity and adheres to the rotator holder.
