Abstract:
An image heating apparatus comprising:an endless movable member; a coil for generating a magnetic flux, wherein eddy current is generated in said movable member by the magnetic flux generated by said coil, by which said movable member generates heat; a core for guiding a magnetic flux; a back-up member for forming a nip with said movable member and wherein a recording material carrying an image is fed by said nip, and the image on the recording material is heated by the heat from said movable member; and temperature detecting means for detecting a temperature of said movable member; wherein a power supply to said coil is controlled on the basis of an output of said temperature detecting means, and said temperature detecting means includes a temperature sensor and an elastic supporting member for supporting said temperature sensor, and said temperature detecting means is contacted to said movable member by its elasticity, and wherein said core is sandwiched by said coil at a position upstream of said nip with respect to a movement direction of an outer periphery of said movable member, and said temperature detecting means is disposed downstream of said nip.
