摘要：
A fixing device temperature control method is performed by a fixing device including a heat conductor contacting and heating an unfixed toner image formed on a recording medium, a heater disposed opposite and heating the heat conductor, and a pressing roller pressed against the heat conductor to form a fixing nip between the heat conductor and the pressing roller through which the recording medium is conveyed. The method includes detecting a temperature of the pressing roller and controlling an input voltage to the heater based on the detected temperature of the pressing roller to maintain a temperature of the recording medium discharged from the fixing nip at a target temperature.
