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.
