Abstract
Provided is an image heating device that heats an image in a nip portion, including: a film; a heater; a roller that forms the nip portion with the film; a backup member; regulating members that regulate a movement of the film and move along with the backup member; and a frame that includes a guide portion to insert the regulating members and a shaft of the roller. The roller includes an elastic layer that is deformed by being pressed from a side which the film is placed, such that a distance between a rotation axis of the roller and the nip portion decreases, and that a volume of the elastic layer decreases. The guide portion guides so that the regulating members move more to a downstream side in a conveying direction of the recording material as the regulating members approach the rotation axis of the roller.
