Fixing device and image forming apparatus

An image forming apparatus comprising:

• an image forming unit that forms an image on a recording material;
• a belt member that moves in a circulating manner;
• a fixing member that faces an outer peripheral surface of the belt member and rotates, wherein the belt member and the fixing member form a fixing nip portion therebetween in which the image formed on the recording material is fixed to a recording material;
• and
• a separating pad portion that is disposed on an inner periphery of the belt member and includes a pressing surface which presses the fixing member at downstream of the fixing nip portion in a moving direction of the belt member, the separating pad portion being configured to separate the recording material from the fixing member,
• wherein the pressing surface of the separating pad portion curves so as to protrude toward the fixing member as approaching a central portion thereof in a rotation axis direction of the fixing member from both end portions thereof in the rotation axis direction,
• wherein the pressing surface of the separating pad portion includes an upstream end portion and a downstream end portion in the moving direction, and
• wherein the upstream end portion and the downstream end portion curve so as to protrude toward an upstream side in the moving direction as approaching the central portion in the rotation axis direction from the both end portions in the rotation axis direction.
