    摘要： An image heating apparatus includes a heater and a film movable together with a recording material carrying an image so that the image on the recording material is heated by heat from the heater through the film. A guiding member guides a surface of the film that contacts the heater, and the guiding member has a surface with projections effective to reduce a contact area between the guiding surface and the film. In addition, a lubricant is supplied between the guiding surface and the film so as to reduce frictional contact.
