PROBLEM TO BE SOLVED: To increase the heat supply efficiency for a recording material and secure the peelability of the recording material in fixing an image formed on the recording material.SOLUTION: An endless pressure belt 520 is disposed in opposition to a heating roll 510 incorporating a heating source and a pressing member 70 for forming a fixing nip part N is attached inside the pressure belt 520 by pressing the pressure belt 520 to the heating roll 510. At an opposed surface 700 facing an inner peripheral surface of the pressure belt 520 of the pressing member 70, a first opposed surface 701, a second opposed surface 702, a third opposed surface 703 and a fourth opposed surface 704 are continuously formed from the upstream side in a conveying direction A of paper P. A first projection is constituted by the fourth opposed surface 704 for constituting the nip part N, a second projection is constituted by the first opposed surface 701 and the second opposed surface 702, and a recess is formed by the third opposed surface having a concave surface. |
