Disclosed is an image forming apparatus that includes a recording head, a liquid tank, a first flow path, a second flow path, a pressure regulation unit, a third flow path, and a liquid supply unit. The pressure regulation unit varies fluid resistance in accordance with a remaining amount of liquid inside the liquid tank, decreases the fluid resistance if the remaining amount of the liquid is equal to or greater than a predetermined amount, increases the fluid resistance if the remaining amount of the liquid is less than the predetermined amount, and supplies the liquid with the liquid supply unit to eject liquid droplets from the recording head, thereby generating a circulation flow that flows through the third flow path and the flow path of the pressure regulation unit.
