摘要： A fixing device includes a tubular rotator and a first heater disposed inside the tubular rotator and extended in a longitudinal direction of the first heater. The first heater heats the tubular rotator. A second heater is disposed inside the tubular rotator and extended in a longitudinal direction of the second heater. The second heater heats the tubular rotator. A heating adjuster is interposed between the first heater and the second heater. The heating adjuster adjusts heat conduction from the first heater to the second heater. A joint combines the heating adjuster with the second heater.
