An image heating apparatus has a magnetic flux generator for generating a magnetic flux; a heat generation member for generating heat by the magnetic flux generator; a magnetic flux adjustor for adjusting an effective magnetic flux region toward the heat generation member with respect to a widthwise direction which is perpendicular to a feeding direction of a material to be heated, wherein the material to be heated is heated by heat generation of the heat generation means; wherein the magnetic flux adjustor includes a magnetic flux adjusting member and moving member for moving the magnetic flux adjusting member, and wherein a temperature distribution in the heat generation member with respect to the widthwise direction is adjusted by moving the flux adjusting member to a predetermined magnetic flux adjusting position by the moving member; and a discriminator for discriminating whether the effective magnetic flux region corresponds to a size of the material to be heated or not when the magnetic flux adjusting member is at the predetermined magnetic flux adjusting position, wherein a number, per unit time, of materials to be heated which are passed through the heating apparatus is decreased. |
