摘要:
An image heating apparatus includes a coil for generating magnetic flux; an image heating member, comprising an electroconductive layer which generates heat by eddy current generated by the magnetic flux from the coil, for heating an image on a recording material; energization control means for controlling energization of the coil so that a temperature of the image heating member is a target image heating temperature Tf (° C.); and a heat pipe contactable with the image heating member. The electroconductive layer has a Curie temperature Tc satisfying the following relationship: Tf≦Tc≦Tf+Qmax (W)×Rh (° C./W),wherein Qmax (W) represents a maximum amount of heat transport, and Rh (° C./W) represents a value of heat resistance of the heat pipe immediately after an occurrence of dryout.
