Image heating apparatus with related image heating member and heat pipe

Abstract

An image heating apparatus includes a coil for generating magnetic flux and an image heating member. The image heating member comprises 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. The image heating apparatus further comprises an energization control device for controlling energization of the coil so that a temperature of the image heating member is a predetermined temperature Tf (° C.), and a heat pipe contactable with the image heating member. The electroconductive layer has a Curie temperature Tc so that the relation Tf≦Tc≦Tf+Qmax (W)×Rh (° C./W) is satisfied, wherein Qmax (W) represents a maximum amount of heat transport, and Rh (° C./W) represents a value of heat resistance of the heat pipe at a dryout occurrence temperature of the heat pipe.
