摘要：
An image heating apparatus includes a coil for generating a magnetic flux by a current flowing therethrough; an image heating member having an electroconductive layer in which an eddy current is produced by the magnetic flux by which heat is generated, to heat an image on a recording material; an electroconductive magnetic flux adjusting member movable from a first position and a second position to decrease the eddy current produced in the image heating member by the magnetic flux; a sensor for sensing the temperature of the image heating member; and a controller for controlling electric power supplied to the coil on the basis of an output of the sensor. The controller changes an electric power condition to be supplied to the coil before start of the movement from the first position to the second position of magnetic flux adjusting member.
