Abstract
An image heating apparatus capable of compatibly realizing enhancement of durability of a heat rotation member heated by magnetic flux from magnetic flux generation means and early rise up of the image heating apparatus to a heatable temperature includes magnetic flux generation means, heating means, drive means, pressure rotation member, and control means. The control means controls power supply to the magnetic flux generation means and the heating means and rotational drive of the drive means. The control means effects control so that rotational drive of the heat rotation member and the pressure rotation member and power supply to the magnetic flux generation means are stopped until a temperature of the pressure rotation member reaches a predetermined value after power supply to the heating means is effected at the time of startup of the image heating apparatus.
