ABSTRACT:
An image heating apparatus includes magnetic flux generating means; a rotatable heat generation member for generating heat by a magnetic flux generated by the magnetic flux generating means to heat a recording material; a magnetic flux adjusting member, disposed between the magnetic flux generating means and the heat generation member, for adjusting a magnetic flux effective region for the heat generation member, with respect to a longitudinal direction which is perpendicular to a feeding direction of the recording material; moving means for moving the magnetic flux adjusting member to a predetermined magnetic flux adjusting position to adjust a temperature distribution of the heat generation member with respect to the longitudinal direction; and a drive receiving portion, disposed at opposite end portions of the magnetic flux adjusting member, for receiving a driving force from the moving means.
