Abstract:
An image heating device includes a restricting member that restricts a lateral shift of a film in a longitudinal direction in a manner in which an edge surface of the film comes into contact with the restricting member when the film laterally shifts, a roller that forms a nip portion, a frame that has a groove in which the restricting member and the roller are inserted, and a pressurizing spring that pressurizes the restricting member and the roller. The restricting member includes a grooved portion, and protrusions that restrict inclination of the restricting member are formed on the grooved portion. When a pressure is applied to the restricting member and the roller, some of the protrusions are in contact with the frame, the other protrusions are not in contact with the frame, and a height of the some of the protrusions is more than a height of the other protrusions.

Claim (Index 1):
An image heating device for heating an image formed on a recording material while interposing and conveying the recording material at a nip portion, the image heating device comprising:\n a tubular film; a restricting member that faces an edge surface of the film at an end portion of the film in a longitudinal direction and that restricts a lateral shift of the film in the longitudinal direction in a manner in which the edge surface of the film comes into contact with the restricting member when the film laterally shifts in the longitudinal direction; a roller that is in contact with an outer surface of the film and that forms the nip portion between the roller and the film; a frame that holds the restricting member and the roller and that has a groove in which the restricting member and the roller are inserted; and a pressurizing spring that pressurizes the restricting member and the roller, wherein the restricting member includes a grooved portion for inserting the restricting member in the frame, and a plurality of protrusions that restrict inclination of the restricting member are formed on the grooved portion, and wherein, when a pressure under which the image is heated is applied to the restricting member and the roller by the pressurizing spring, some of the plurality of protrusions are in contact with the frame, the others of the plurality of protrusions are not in contact with the frame, and a height of the some of the plurality of protrusions is more than a height of the others of the plurality of protrusions.
