A fixing device comprising:

• a rotatable endless belt;
• a rotatable member configured to contact an outer peripheral surface of the belt, the rotatable member forming a nip portion in cooperation with the belt, nipping and conveying a recording material on which a toner image is formed in the nip portion and fixing the toner image onto the recording material by application of heat and pressure;
• a nip forming member configured to contact an inner peripheral surface of the belt and form the nip portion by being disposed opposite to the rotatable member,
• wherein the nip forming member is a non-rotatable member and includes a contact area in contact with the inner peripheral surface of the belt,
• wherein the contact area includes a downstream end portion with respect to a conveyance direction of the recording material,
• wherein the downstream end portion includes a central portion and both end portions with respect to a widthwise direction of the belt, and
• wherein the central portion locates downstream of the both end portions with respect to the conveyance direction.
