Abstract
A fixing apparatus includes a first pressing roller, a belt wound around the first pressing roller, a second pressing roller, and a roller position changer that changes a position of the second pressing roller. The second pressing roller faces the first pressing roller across the belt and forms a fixing nip portion between itself and the belt. At least one of the first pressing roller and the second pressing roller includes a core metal and a foam body covering the core metal. The roller position changer changes a position of the second pressing roller based on a kind of print medium to change a peak surface pressure of the fixing nip portion, such that a range where maximum shearing strain occurs from an interface between the core metal and the foam body in the foam body is a predetermined range.
