Abstract
An image heating apparatus includes a heating rotatable member for heating an image on a recording material in a heating nip; a magnetic flux generator for generating a magnetic flux for induction heat generation in the heating rotatable member; a magnetic flux confining device for confining the magnetic flux directed toward a predetermined region of the heating rotatable member from the magnetic flux generator; and a moving device for repeatedly moving the magnetic flux confining device during a heating operation between the operating position and a retracted position retracted from the operation position, when the recording material which has a predetermined width overlapping with a part of the predetermined region is continuously heated by the apparatus.
