Abstract:
In a fixing device according to the disclosure, a first surface of a restriction member is inclined so that, as the first surface goes further away from a nip portion, the first surface inclines toward a direction coming closer to an edge surface of the film, and the first surface is inclined so that, as the first surface comes downstream in the conveying direction, the first surface inclines toward a direction going further away from the edge surface of the film. A second surface is inclined so that, as the second surface comes closer to a center in the rotational axis direction of the film, the second surface inclines toward a direction coming closer to a roller, and inclines in a direction going downstream in the conveying direction.

Claim (Index 1):
A fixing device comprising:\n a cylindrical film; a nip portion forming member configured to be in contact with an inner surface of the film; a roller configured to form a nip portion with the nip portion forming member across the film; and a restriction member configured to restrict a shifting movement of the film in a rotational axis direction of the roller, the restriction member including a first surface that is opposed to an edge surface of the film and with which the edge surface comes into contact when the film makes the shifting movement, and a second surface opposed to an inner surface of the film and configured to guide rotation of the film, wherein a recording material on which an image is formed is heated while being conveyed in the nip portion, and the image is fixed to the recording material, wherein as viewed in a conveying direction of the recording material, the first surface is inclined so that, as the first surface goes further away from the nip portion in a direction perpendicular to both the conveying direction and the rotational axis direction, the first surface inclines toward a direction coming closer to the edge surface of the film, and as viewed in the perpendicular direction, the first surface is inclined so that, as the first surface comes downstream in the conveying direction, the first surface inclines toward a direction going further away from the edge surface of the film, and wherein as viewed in the conveying direction, the second surface is inclined so that, as the second surface comes closer to a center in the rotational axis direction of the film, the second surface inclines toward a direction coming closer to the roller, and as viewed in the perpendicular direction, the second surface is inclined so that, as the second surface comes closer to the center of the film, the second surface inclines toward a direction going downstream in the conveying direction.
