Abstract
A fixing device includes an endless belt, a rotatable pressing member, a pad member inside of the belt, and a sliding member held by the pad member and sliding on an inner circumferential surface of the belt in a nip. The rotatable pressing member nips and feeds a recording material in the nip in cooperation with the belt and fixes a toner image on the recording material by applying heat and pressure. The sliding member includes a base material layer on which a plurality of projections projecting toward the rotatable pressing member are formed on a side sliding with the belt and a sliding layer provided on an outer surface of the plurality of projections. A shape of a surface of the sliding layer is a curved surface and a radius of curvature R of the curved surface satisfies 300 μm≤R≤850 μm.
