A fusing unit which is provided on a printing path, and which fuses an image onto a printing medium, includes: a heating roller (20) having a core member (21), a rubber layer (23) which is formed to have a predetermined thickness on an outer circumference of the core member (21), a release layer (25) which is formed on the outer surface of the rubber layer (23) and prevents the printing medium from being adhered to the heating roller (20) during a fusing process, and a heating coil (10) which is embedded inside the rubber layer (23) and applies heat to the rubber layer (23); a pressing roller (30) which is disposed to face the heating roller (20), and presses the printing medium in collaboration with the heating roller (20); and an elastic member (40) which elastically biases the pressing roller (30) toward the heating roller (20) and forms a fusing nip (N F ) to have a predetermined width between the heating roller (20) and the pressing roller (30). |
