Abstract
A fixing apparatus includes 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 arranged in a line extending in the generatrix direction. A toner image is fixed on a recording material by heat which the conductive layer generates by electromagnetic induction. In the generatrix direction, a protruded portion is provided on an end surface of the first magnetic member and a recessed portion is provided in an end surface of the second magnetic member. The protruded portion and the recessed portion are disposed so as to oppose each other and overlap each other in the generatrix direction.
