摘要： A pressure member contacts a heating member to form a nip part where a recording material is heated and pinched-conveyed, and includes a first elastic layer and a second elastic layer 24b having a higher thermal conductivity than that of the first elastic layer. An elastic layer is formed of a 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, when using the pressure member to contact the heating member to form the nip part, it is possible to reduce the difference between a center nip width and an end-portion nip width of the nip part.
