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.

摘要： A fusing device includes a pressing member, a belt member to rotate in contact with the pressing member, a nip forming member to support the belt member so that nip areas are formed on the pressing member and the belt member at contacting portions thereto, a heating member disposed away from the nip areas, to heat the belt member, and a tension application member to stiffen the belt member so that the heating member is tightly contacted with the belt member. The heating member includes a plate type heating element which is arranged at an upstream side of the nip areas, and to contact an inner circumference of the belt member, in an advancing direction of the fusing belt. The effective width of then nip areas increases, and the increased pressure is exerted to the nip areas, because the fusing belt enters a location where the nip areas are formed in a heated state. Furthermore, heating efficiency of the fusing belt is increased, because the fusing belt is heated while in a tight contact with the heating member. As a result, fusing performance is enhanced.

摘要： A fixing device includes a fixing roller, a fixing belt which is made to rotate by a rotation force received from the fixing roller, a nip forming unit to form a nip zone at a contact area between the fixing roller and the fixing belt, and a first heating unit, which is separated from the nip zone, to apply heat to the fixing belt. The nip zone and the heating unit are separated, so that the heating unit can be prevented from being broken as a result of the pressurization and thermal deformation.
