Abstract
A heating device includes an endless rotator that rotates in a rotation direction and a heater that contacts an inner circumferential surface of the endless rotator and extends in an axial direction of the endless rotator. An elastic body contacts the inner circumferential surface of the endless rotator and is disposed downstream from the heater in the rotation direction of the endless rotator. A holder holds the heater and the elastic body. A pressure rotator is disposed opposite the heater and the elastic body via the endless rotator to form a nip between the endless rotator and the pressure rotator. A motion restrictor is mounted on the holder. The motion restrictor restricts motion of the heater downstream in the rotation direction of the endless rotator.
