Abstract
A fixing device includes a fixing rotator and a slider that slides over the fixing rotator. A cam presses the slider against the fixing rotator. The cam includes a cam rear disposed opposite a rear end of the fixing rotator in an axial direction thereof and a cam front disposed opposite a front end of the fixing rotator in the axial direction thereof. A controller rotates the cam to a first slide position where the cam rear presses the slider against the fixing rotator, a second slide position where the cam rear and the cam front press the slider against the fixing rotator, a third slide position where the cam front presses the slider against the fixing rotator, and an isolation position where the cam rear and the cam front do not press the slider against the fixing rotator.
