Abstract:
1. An image heating apparatus comprising: a heating member; and a pressure roller that contacts said heating member, said pressure roller including a metal core, a first elastic layer, and a second elastic layer provided on the outside of the first elastic layer, the second elastic layer having a thermal conductivity higher than the thermal conductivity of the first elastic layer, wherein the heating member and the pressure roller are configured to pinch and convey a recording material bearing a toner image thereon so that the recording material is heated, and wherein each of the end portions of the second elastic layer is thicker than a center portion of the second elastic layer in an axial direction of said pressure roller, and wherein the thickness of the first elastic layer gradually decreases from the center portion of the first elastic layer to the end portions of the first elastic layer in an axial direction of the pressure roller.
