Abstract:
A fixing apparatus includes a cylindrical heating rotating member, a nip portion forming member having first and second surfaces, and provided in a hollow portion of the heating rotating member so that the first surface contacts an inner surface of the heating rotating member, and a roller that, sandwiches the heating rotating member with the nip portion forming member to form a nip portion. A plurality of recessed portions are on the first surface, so a size of an area in which the first surface is in contact with the heating rotating member in an upstream area of the nip portion is less than a size of the area in which the first surface of the nip portion forming member is in contact with the heating rotating member in a downstream area of the nip portion with respect to a center of the nip portion.

Claim (Index 7):
A fixing apparatus comprising:\n a heating rotating member having a cylindrical shape; a nip portion forming member that includes a first surface and a second surface opposite to the first surface, and that is provided in a hollow portion of the heating rotating member so that the first surface is in contact with an inner surface of the heating rotating member; and a roller that, together with the nip portion forming member, sandwiches the heating rotating member to form a nip portion, wherein the nip portion is an area in which both the nip portion forming member and the roller contact with the heating rotating member in a rotation direction of the heating rotating member, a recording material on which an image is formed is heated by passing between the nip portion and the heat rotating member and the image is fixed on the recording material, and a plurality of recessed portion is provided on the first surface of the nip portion forming member, so that a size of an area in which the first surface of the nip portion forming member is in contact with the heating rotating member in an upstream area of the nip portion is less than a size of the area in which the first surface of the nip portion forming member is in contact with the heating rotating member in a downstream area of the nip portion with respect to a center of the nip portion in a rotation direction of the heating rotating member.
