Claim Text:
1. A fixing apparatus for fixing a toner image on a recording material, the apparatus comprising: a rotating member including a conductive layer; a helical coil arranged inside the rotating member, a helical axis of the coil extending in a generatrix direction of the rotating member; and a magnetic member provided inside the coil, the magnetic member including a first magnetic member and a second magnetic member that are aligned in a line in a direction along the generatrix direction, wherein a magnetic field is formed by a current flowing in the coil wherein the toner image is fixed on the recording material by heat which the conductive layer generates by electromagnetic induction in the magnetic field, wherein a protruded portion is provided on an end surface of the first magnetic member in the generatrix direction, and a recessed portion is provided in an end surface of the second magnetic member in the generatrix direction, and wherein the protruded portion and the recessed portion are disposed so as to oppose each other and overlap each other in the generatrix direction.
