Abstract
A fixing device includes a fixing member that fixes a toner image to a recording medium, a pressure member that forms, together with the fixing member, a pressure portion through which the recording medium carrying the toner image yet to be fixed passes, and a heating member including a heating layer that generates heat when energized and an insulating layer that encloses the heating layer so as to electrically insulate the heating layer. The heating member has a curved shape along an inner peripheral surface of the fixing member, in a state in which no external force is applied, and is in contact with the inner peripheral surface of the fixing member.
