Claim Text:
1. A fixing apparatus comprising: a fixing heater that performs heat fixing; a control unit that controls the fixing heater based on control patterns in each of which turn-on period of the fixing heater and turn-off period of the fixing heater are set according to a control cycle with a half cycle of alternate current supplied from alternate current power supply being as one unit; a temperature-detecting unit that detects temperature of the fixing heater; and a voltage-value-acquiring unit that acquires a voltage value that is applied to the fixing heater, wherein the control unit is configured so as to turn the fixing heater on or off using a combination of the control patterns each satisfying a predetermined standard during each control period of time that is integral multiplication of the control cycle according to the temperature of the fixing heater detected by the temperature-detecting unit and the voltage value, which is allied to the fixing heater, acquired by the voltage-value-acquiring unit.
