A fixing device 2 includes a primary fixing device 5 disposed in a transporting path 4 for a recording material 3, and a secondary fixing device 6 disposed in the downstream of the primary fixing device 5. The recording material is passed through only the primary fixing device 5 after an image is recorded on an front surface of the recording material 3. Subsequently, an image is recorded on a rear surface of the recording material 3 and the recording material is passed through the primary fixing device 5 and the secondary fixing device 6. The fixing device 2 includes a primary ejection path 7 for ejecting the recording material 3 having passed through the primary fixing device 5 and a secondary ejection path 8 for ejecting the recording material 3 having passed through the primary fixing device 5 and the secondary fixing device 6 in this order.
