PROBLEM TO BE SOLVED: To provide a fixing device capable of suppressing energy loss due to heat dissipation to the outside of the fixing device as much as possible with a simple configuration, and an image forming apparatus including the fixing device.SOLUTION: A fixing device 15 includes an upper housing 15a having a heating roller 20a stored therein, and a lower housing 15b having a pressure roller 20b stored therein. A heating-side heat insulating plate 31a is arranged between an inner surface of the upper housing 15a and the heating roller 20a, and a pressure-side heat insulating plate 31b is arranged between an inner surface of the lower housing 15b and the pressure roller 20b. A distance d2 between the pressure roller 20b and the pressure-side heat insulating plate 31b is larger than a distance d1 between the heating roller 20a and the heating-side heat insulating plate 31a. |
