Abstract
An image heating apparatus is provided with: PA1 a moving member having an electrically conductive layer and arranged to move together with a recording medium, an exciting coil for generating a magnetic flux, wherein the magnetic flux generated by the exciting coil generates eddy currents in the moving member and the eddy currents make the moving member generate heat, wherein the heat of the moving member heats an image on the recording medium, a magnetic member for guiding the magnetic flux generated by the exciting coil, wherein the moving member and the magnetic member form a substantially closed magnetic circuit, wherein an angle .theta. rad! formed between a principal line of magnetic force directed from the magnetic member to the moving member and a principal line of magnetic force directed from the moving member to the magnetic member is determined to be 0<.theta.<.pi..
