摘要： 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.

摘要： A fixing device includes a fixing belt that is endless and rotates in a rotation direction. A pressure rotator presses against the fixing belt to form a nip between the fixing belt and the pressure rotator. A heater is disposed opposite an inner circumferential surface of the fixing belt and heats the fixing belt. A contact member contacts the fixing belt partially in a longitudinal direction of the fixing belt. A holder holds the heater. The heater contacts the holder with a first contact amount in a first span in a longitudinal direction of the heater, where the contact member contacts the fixing belt. The heater contacts the holder with a second contact amount, that is greater than the first contact amount, in a second span in the longitudinal direction of the heater, where the contact member does not contact the fixing belt.

摘要： A fixing device includes a fixing rotator, a first heat generator and a second heat generator that heat the fixing rotator, and a support disposed inside the fixing rotator. A reflector, interposed between the support and each of the first heat generator and the second heat generator, reflects light radiated from the first heat generator and the second heat generator toward the fixing rotator. The reflector includes a body mounted on the support and a shield portion projecting from the body toward the first heat generator and the second heat generator to shield the fixing rotator from the first heat generator and the second heat generator. An electric circuit is connected to the first heat generator and the second heat generator. A heat generation restrainer is provided in the electric circuit to restrict heat generation in the electric circuit.

摘要： A pressure adjuster for changing pressure between a plurality of opposed bodies pressed against each other includes a cam rotatable in a given direction of rotation and having a top dead center on an outer circumferential surface thereof that is distanced farthest from a rotation axis of the cam. A driver is connected to the cam to drive and rotate the cam. A cam rest contacts the cam and is connected to one of the plurality of opposed bodies. A cam regulation assembly is connected to the cam to regulate rotation of the cam at least when the top dead center of the cam passes a contact position where the cam contacts the cam rest.
