The invention relates to a fixing device, comprising a heating element, a heat-conductive film, a pressure element, two film regulating elements arranged at two ends of the heat-conductive film and a roller. The heat-conductive film is hollow tubular, the two ends of which are respectively loosely and coordinately sleeved on the two film regulating elements; the pressure element is inserted in the heat-conductive film and contacted with the two film regulating elements, wherein, the pressure element comprises a horizontal contact surface contacted with the inner surface of the heat-conductive film; the heating element is inserted in the heat-conductive film and heats the heat-conductive film with radiant heating method; the roller is adjacently arranged on the horizontal contact surface of the pressure element and supported with the horizontal contact surface through the heat-conductive film, rotation of the roller can drive the heat-conductive film to rotate, a fixing area is jointly defined between the supported part of the heat-conductive film and the horizontal contact surface and the roller. The fixing device is very applicable to practicalities and has the advantages of improving the heat transfer efficiency, reducing the energy consumption and reaching the working temperature in a short time.
