1. A fixing member configured to heat a toner image borne on a recording material and formed in a rotatable tubular shape, the fixing member comprising:
a conductive layer configured to generate heat by an induced electromotive force when an alternating magnetic field is created, the conductive layer including a plurality of conductive elements that are electrically disconnected each other in a direction of a generatrix of the fixing member,
wherein, in the direction of the generatrix, when an area through which the recording material with a maximum width conveyable to the fixing member passes is referred to as a first area, the first area includes a central area and an end portion area,
wherein the central area includes a central portion of the first area in the direction of the generatrix,
wherein the end portion area includes an end portion of the first area in the direction of the generatrix,
wherein a resistance value of each of the plurality of conductive elements disposed in the central area is a first resistance value, and
wherein a resistance value of each of the plurality of conductive elements disposed in the end portion area is a second resistance value that is lower than the first resistance value.
