Fixing apparatus and image forming apparatus having the same

A fixing apparatus for fixing an image onto a recording material, the fixing apparatus comprising:

• a heating rotary member;
• a film having a cylindrical shape;
• and
• a pressure member that presses the film from inside the film toward the heating rotary member to form a nip portion which is an area where the heating rotary member and the film contact, the pressure member including a metallic member extending from an upstream side of a center of the nip portion to a downstream side of the center of the nip portion in a recording material conveyance direction,
• 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, and
• wherein in a cross section perpendicular to a rotation axis direction of the heating rotary member, a center of gravity of the metallic member is on the upstream side of the center of the nip portion in the recording material conveyance direction.
