Abstract
A method of driving a liquid ejection head adapted to apply a voltage to the liquid ejection head to eject a liquid including a polymer is provided. The method includes raising the voltage from a first voltage to a second voltage; raising the voltage from the second voltage to a third voltage at a gradient larger than that in raising the voltage from the first to the second voltage, and then holding the voltage at the third voltage; dropping the voltage from the third voltage to a fourth voltage, and then holding the voltage at the fourth voltage; raising the voltage from the fourth voltage to a fifth voltage, and then holding the voltage at the fifth voltage; dropping the voltage from the fifth voltage to a sixth voltage, and then holding the voltage at the sixth voltage; and raising the voltage from the sixth voltage to a seventh voltage.
