Abstract
A fixing apparatus includes a nip forming member that contacts an inner surface of a tubular film and forms a nip together with a roller via the film. The roller has a region where a diameter of the roller gradually increases in a direction from a center to each of ends of the roller with respect to a generatrix direction of the film. The nip forming member has a protruding portion, protruding toward the roller and extending in the generatrix direction, that is provided on at least one of an upstream side and a downstream side in the nip in a conveying direction of the recording material. Ends of the protruding portion in the generatrix direction are positioned at a larger distance from a center of the nip in the conveying direction than a central of the protruding portion in the generatrix direction.
