PROBLEM TO BE SOLVED: To provide a belt fixing device constituted so that the driving load of a pressure roller at the time of warming-up can be reduced in the case of using lubricant. SOLUTION: The belt fixing device 10 is provided with an endless sheet-like fixing belt 12 which is stretched to be laid between a rotatable heat roller 14 and a nip forming member 20 fixedly arranged so as not to be rotated, and whose inner surface is coated with the lubricant such as grease and oil, and a rotary-driven pressure roller 40 which is brought in press contact with the nip forming member 20 across the fixing belt 12 and which has a contact part with the fixing belt 12 functioning as a fixation nip 21, the fixing belt 12 is rotated in accordance with the rotary driving of the pressure roller 40, and the pressure roller 40 is brought in press contact with the nip forming member 20 with a press-contact force so that the pressure roller 40 can be rotated while slipping on the fixing belt 12 at least at the time of warming-up.
