A primary temperature detector and a secondary temperature detector detect a temperature of the fixing rotator. A tertiary temperature detector detects a temperature of a pressure rotator. A controller selectively performs a primary control mode to de-energize the tertiary heater and a secondary control mode to connect the secondary heater and the tertiary heater in series to energize the primary heater, the secondary heater, and the tertiary heater. The controller energizes the secondary heater and the tertiary heater in the secondary control mode based on the temperature of the fixing rotator and the pressure rotator detected by the secondary temperature detector and the tertiary temperature detector, respectively.

摘要： A fixing device for fixing an unfixed toner image on a recording medium includes a fixing member, a pressure member, a sheet guide, and a pressure adjusting mechanism. The fixing member heats the unfixed toner image on the recording medium. The pressure member is disposed opposite the fixing member and presses against the fixing member to define a fixing nip through which the recording medium bearing the unfixed toner image passes to fix the unfixed toner image onto the recording medium. The position of the fixing nip is changeable. The sheet guide disposed adjacent to the pressure member guides the recording medium to the fixing nip and moves in conjunction with movement of the pressure member. The pressure adjusting mechanism operatively connected to the pressure member adjusts an amount of engagement of the pressure member relative to the fixing member. An image forming apparatus includes the fixing device.
