A pressure member contacts with a heating member 23 to form a nip part N where a recording material P is heated and pinched-conveyed, and includes a first elastic layer 24a and a second elastic layer 24b having higher thermal conductivity than that of the first elastic layer. An elastic layer is formed in combination of the first elastic layer and the second elastic layer so that the thickness of the second elastic layer at the end portion is thicker than the thickness of the second elastic layer at the center portion in a longitudinal direction perpendicular to a recording material conveyance direction. Accordingly, in the pressure member contacting with the heating member to form the nip part, it is possible to reduce a difference between a center nip width and an end-portion nip width of the nip part.
