PROBLEM TO BE SOLVED: To provide an image forming apparatus that can stably maintain a pressed state between a pressure roller and an endless belt.SOLUTION: A fixing unit 5 comprises a lower frame 20, a pressure roller 21, and fixing members 41. The fixing members 41 are each arranged above each of bearing parts 53 of the pressure roller 21, and attached to each of upper faces 36A of each of support parts 36 of the lower frame 20. The fixing members 41 each include a lower face 60A of a contact part 60 in contact with an upper face 53A of the bearing part 53 of the pressure roller 21. When a driving force is applied from a large-diameter gear part 72 to a pressure gear 71 and an upward force F is applied to the pressure roller 21, the fixing members 41 regulate an upward movement of the bearing parts 53.SELECTED DRAWING: Figure 6 |
