A method of driving a piezoelectric inkjet printhead, the method including: applying a forward voltage to a piezoelectric body of the piezoelectric actuator; and applying a driving pulse to the piezoelectric body based on the forward voltage as a reference voltage in order to eject ink. Accordingly, the piezoelectric body can be driven in a push mode and in a pull mode without applying a backward voltage to the piezoelectric body.
