Abstract
An image heating apparatus for heating a toner image formed on a recording material includes a first rotatable member contactable to the toner image; and a heating unit, including a second rotatable member rotating while contacting a surface of the first rotatable member, for heating the first rotatable member. The toner image on the recording material is heated by receiving heat from the first rotatable member heated by the heating unit. The image heating apparatus further includes a potential controller for maintaining a polarity of a surface potential of the second rotatable member so as to be opposite to a charge polarity of the toner.
