摘要： A belt fixing device includes a fixing roller, a heating roller, a fixing belt stretched between the fixing roller and the heating roller, a pressing roller pressing the fixing roller through the fixing belt, and a temperature detection unit detecting the surface temperature of the fixing belt. In at least one end portion of the heating roller in an axial direction, a ring regulating skewed movement of the fixing belt toward an axial end, and a belt tension adjusting unit adjusting tension of the fixing belt are provided. The temperature detected by the temperature detection unit is stored in a storage unit. When the belt tension adjusting unit releases belt tension, a control unit controls a rotation stop position of the fixing belt on the basis of the belt temperature stored in the storage unit.
