A recording apparatus includes an electrolytic capacitor for stabilizing the head power source voltage, a transistor for charging the electrolytic capacitor, a transistor for discharging the electrolytic capacitor, a push-pull circuit, a resistor for controlling the charging/discharging current to the electrolytic capacitor, and a resistor for dividing the head power source voltage. The power supply to the head is turned on with the head power source voltage increased by the capacitor.
