An invented image forming apparatus includes a fixing unit for fixing a developer image transferred onto a conveyed medium; a temperature detecting unit for detecting a temperature of said fixing unit, a first power supply controller for controlling power supply to said fixing unit based on the detected result of the temperature detecting unit, a second power supply controller for controlling power supply to said fixing unit based on a preset value, a medium detection unit for detecting a medium to be conveyed, and a power supply operation controller for switching control done between said first power supply controller and said second power supply controller based on a position of the medium detected with said medium detection unit. The image forming apparatus can reduce impairment of settling rate of the developer images at the second half of the recording paper during the fixing process.
