Zusammenfassung:	An image forming apparatus includes a print head, a main control unit, a head control unit, and a head unit power supply to generate a voltage to be supplied to the head control unit. The main control unit checks whether the main control unit is normally started up. The head control unit includes an operation checker to check whether the head control unit normally operates if the main control unit is normally started up and the head control unit is supplied with a check voltage, a head power supply generator to generate a voltage to be supplied to the print head if the head control unit normally operates, and a status detector to detect a status of the print head based on the voltage supplied to the print head, and control the voltage to be supplied to the head control unit depending on the status detected by the status detector.
