PROBLEM TO BE SOLVED: To provide an image forming device having a fixing device, in which energy-saving effects in both-sided image formation is improved, a roller-shaped fixing member on the surface side is prevented from causing high-temperature fixing offset, and a transfer member is prevented from curling during fixing. SOLUTION: The image-forming device has the fixing device. A heating means is disposed in the roller-shaped fixing member which is on the surface side of the fixing device. In addition, an outer heat roller member, which has a heating means in the inside, is disposed in pressure-contact with the roller- shaped fixing member, which is located on the rear side of the fixing device. |
