Abstract:
Disclosed is a fixing device including: a fixing belt provided across a fuser roller and a heating member in a tensioned state, which fixing belt is rotated; and a tension roller applying a load on the fixing belt from an inner circumferential side of the fixing belt, which tension roller is determined in position on the fixing belt so that a length of the fixing belt upstream of the fixing nip area in a fixing belt rotating direction, from the tension roller to the fixing member, is longer than that downstream of the fixing nip area in the fixing belt rotating direction, from the fixing member to the tension roller.
