Abstract:
An image heating apparatus includes: an image heating roller in a nip; a nip forming member; a heating roller rubbing roller; a moving mechanism for moving the rubbing roller between a spaced position and a rubbing position; and a controller for executing operations in first and second modes. In the first mode, the heating roller is rotated with the rubbing roller in the spaced position and the heating roller in contact with the nip forming member with a target temperature of the heating roller higher than that of the nip forming member. In the second mode, the rubbing roller is contacted with the heating roller, rubbing the surface of the heating roller. The temperature difference in the first mode between the target temperature of the heating roller and that of the nip forming member is larger than the temperature difference when the toner image is heated by the nip.
