摘要： A fixing device includes a fixing roller, a fixing belt which is made to rotate by a rotation force transferred from the fixing roller, a heat source which is mounted inside the fixing belt, a guide member, which is mounted inside the fixing belt, to guide the rotation of the fixing belt, and a belt meander preventing unit, which is mounted on the guide member, to elastically support both sides of the fixing belt and to prevent the fixing belt from meandering. Therefore, the sides of the fixing belt are elastically supported to gently absorb a reaction force acting on the end portion of the fixing belt, and accordingly it is possible to prevent the fixing belt from being damaged and meandering.
