ABSTRACT:
The image heating apparatus includes a cylindrical film, a heating member, and a drive roller, wherein a recording material bearing an image is heated while the recording material is bound and conveyed by the nip portion, and a distance between a contact position between the film and the recording material and a contact position which the film and the drive roller is equal to or less than 3.5 mm over a longitudinal direction of the nip portion, and a line formed by connecting positions at which said film is separated in the longitudinal direction of the nip portion from the recording material in the conveyance direction has an arc shape. Thus a heating process can be executed while suppressing creases in the recording material and a density loss in the image formed on the recording material.
