Patent ID: 8139971

Claim:
An image heating apparatus for an image forming apparatus comprising: a coil; a rotatable image heating member for heating an image by heat generated by a magnetic flux generated by said coil; a temperature detecting member for detecting a temperature of said image heating member; electric power supply control means for controlling electric power supply to said coil in accordance with an output of said temperature detecting member; an execution portion for executing a stand-by mode operation waiting for input of an image forming operation signal for forming an image on a recording material by the image forming apparatus; and a stand-by controller for controlling, in a state that rotation of said image heating member is not rotated during the stand-by mode operation, the electric power supply controlled by said electric power supply control means such that at least a temperature in a temperature detecting region by said temperature detecting member is a predetermined stand by temperature, wherein along no longitudinal line on said image heating member does the temperature of said image heating member exceed Curie temperature on an entirety of the longitudinal line, in a state that said stand-by controller controls the temperature in the temperature detecting region at the predetermined stand-by temperature.
