    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.

    摘要： A fusing device and an image forming apparatus having the same. The fusing device can include a fusing belt, a heat source disposed in an interior of the fusing belt, a supporting member to support at least a portion of an inner peripheral surface of the fusing belt, a press member mounted while opposing the fusing belt to form a fusing nip, and a nip forming part formed with an opening portion to enable heat emitted from the heat source to be transferred to the fusing belt at a position corresponding to the fusing nip. The nip forming part can have at least one gap maintaining part to prevent change of a gap of the opening portion. The nip forming part is provided at the supporting member or a nip forming member mounted between the heat source and the supporting member. Accordingly, a temperature of the fusing belt can rise quickly by directly heating the fusing belt, and deterioration of fusing performance due to deformation of the nip forming member can be prevented.
