摘要:
A fixing apparatus for fixing an image onto recording material, includes a heating rotary member, film of a cylindrical shape, and pressure member configured to press the film from inside the film toward the heating rotary member to form a nip portion as an area where the heating rotary member and film contact. The pressure member includes a metallic member extending from an upstream side of a center in a recording material conveyance direction of the nip portion to a downstream side, wherein the recording material on which the image is formed is conveyed while being heated at the nip portion to fix the image onto the recording material. A center of gravity of the metallic member is on the upstream side of the center in the recording material conveyance direction of the nip portion in a cross-section perpendicular to a rotation axis direction of the heating rotary member.
