A fixing device (20) comprises a flexible endless belt (21) rotated in a prescribed direction to heat and fuse a toner image (T), a rotating member (31) that presses against and rotates the flexible endless belt (21), and a fixed member (26) disposed on an inner circumferential surface side of the flexible endless belt (21) to press against the rotating member (31) via the flexible endless belt (21). A heater (22) is fixedly disposed facing an inner circumferential surface of the flexible endless belt (21) to heat the flexible endless belt (21). The heater (22) includes an opening (22a) opposed to the rotating member (31) that accommodates the fixed member (26). A reinforcing member (23) is fixedly disposed on an inner circumferential surface side of the heater (22) to contact and reinforce the fixed member (26).
