PROBLEM TO BE SOLVED: To improve the heating efficiency of a fixing belt and to stabilize temperature by deterring heat of the fixing belt from being taken away as to a thermal fixing device that heats and presses a recording medium at a nip part where a pair of fixing belts come into contact with each other to fix a toner image on the recording medium. SOLUTION: The thermal fixing device which heats and fixes the toner image on the recording medium 1 is provided with: a pair of endless fixing belts 11 and 12; a pair of rotary members 13 and 14 which are provided on the inner circumferential sides of the fixing belts and are pressed across the fixing belts; a pair of fixed members 15 and 16 which are provided on the inner peripheral sides of the fixing belts and pressed across the fixing belts; and a heating device 17 which heats at least one fixing belt. The fixing belts come into contact with the rotary members and fixed members only at the press-contacting parts of the rotary members and press-contacting parts of the fixed members.
