Abstract:
An induction heating apparatus for heating an image formed on a recording material, comprising:a high frequency current generating means for generating a high frequency current; an excitation coil to which the high frequency current generated by the high frequency current generating means is applied, for generating a magnetic field; a heating member having an endless metal member in which an eddy current is induced by the magnetic field generated by said excitation coil; a temperature detecting element for detecting the temperature of said heating member; control means for controlling an electrical supply to said excitation coil in accordance with the temperature detected by said temperature detecting element; and a band-pass filter connected between said temperature detecting element and said control means, wherein said band-pass filter is provided outside of a width of an endless member in a longitudinal direction of the endless metal member.
