ABSTRACT:
A fixing method and a fixing device is provided in which an unfixed toner image formed on a recording medium is heat-pressure-fixed by using a fixing unit, wherein the unfixed toner image is fixed when the recording medium passes through at least two fixing units arranged in series in a conveying direction of the recording medium. Specific relations are satisfied between a maximum temperature on the recording medium when the recording medium passes through a first fixing unit, a maximum temperature on the recording medium when the recording medium passes through a second fixing unit, a minimum temperature on the recording medium during a time period commencing on ejection of the recording medium from the first fixing unit and ending on entry of the recording medium into the second fixing unit and properties of the toner.
