PURPOSE:To obtain a high-quality image, by pressing a transfer material, which is heated to a temperature lower than the toner fusing temperature, to the toner image on an intermediate transfer material, which is heated to a temperature lower than the toner fusing temperature, by a pressing material heated to a temperature higher than the toner fusing temperature. CONSTITUTION:A toner image T on a toner image carrier 1 is transferred to an intermediate transfer material 5 in a transfer region A. The intermediate transfer material 15 consisting of an endless belt and the toner image on this material 5 are heated to a temperature lower than the toner fusing temperature by a heat roll 7. Heating of a heat press roll 9 in a transfer and fixing region C is so controlled that the temperature of a carrying-in belt 17 and a transfer material is higher than the toner fusing temperature. Therefore, the carrying-in belt 17 and the transfer material are heated to a slightly higher temperature and lower than the toner fusing temperature preliminarily by a transfer material heating plate 10. When the transfer material is pressed to the intermediate tranfer material 5 by a heat press roll 9, the toner image is transferred and fixed to the transfer material surely. |
