摘要：
An unfixed toner image on a transferring and fixing belt is passed through a pair of toner integrating rollers. A surface side of the toner integrated that is in contact with a paper, is heated by a halogen heater to impart a tackiness required for fixing. As a result of this, a temperature of a surface side of the toner that is in contact with the transferring and fixing belt is not as high as a temperature of the surface side of the toner that is in contact with the paper. Therefore, even if the toner is pressurized, and transferred and fixed at a fixing nip, a difference in an area of the toner is small. This enables to achieve a good image quality.
