PROBLEM TO BE SOLVED: To provide an image heating apparatus which can suppress temperature rise in a region where recording material does not pass, and to provide a pressure member which is used for the apparatus, stabilizes conveyability, has high durability, high thermal conductivity, and low hardness. SOLUTION: The pressure member includes: a core metal; an elastic layer containing filler, the elastic layer containing filler whose thermal conductivity λ<SB>y</SB>in the longitudinal direction orthogonal to a recording material conveyance direction is λ<SB>y</SB>≥2.5W/(m.k), and whose ASKER-C hardness of the filler is not more than 60 degrees; and a solid rubber elastic layer whose thermal conductivity λ in a thickness direction is not less than 0.16 W/(m.k) and not more than 0.40 W/(m.k). The solid rubber elastic layer is formed on an outer periphery of the core metal and the elastic layer containing the filler is formed on the outer periphery of the solid rubber elastic layer.
