Abstract
A fusing apparatus includes: a rotating endless belt; a pressing member pressing the belt from an inside of the belt; and a roller forming the fusing nip between the roller and the belt by pressing, from an outside of the belt, a position where the belt faces the pressing member, wherein a surface of the pressing member facing the roller via the belt includes: plane surface, and a curved surface adjacent to the plane surface at a downstream-side end in a conveying direction of the storage medium of the plane surface, and when viewed from a cross-section orthogonal to a central axis of the roller, an upstream-side end of the conveying direction of the plane surface is away from a straight line passing through the central axis of the pressure roller and parallel to the conveying direction, farther than the downstream-side end in the conveying direction of the plane surface.
