摘要： A fuser roller and a fusing unit including the fuser roller are to be used in an image-forming apparatus. The fuser roller includes a tubular fusing portion, an inner tube, and a heating portion. The inner tube is inserted into the fusing portion. The heating portion is installed to enclose an outer surface of the inner tube and press against an inner surface of the fusing portion, and to radiate heat. The fusing portion is surface treated to have a roughness factor of Ra 3-5μm.

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.
