A first activation signal has ejection activation pulses that eject ink from nozzles; a second activation signal has a micro-oscillating activation pulse (non-ejection activation pulse) for inducing pressure fluctuation on ink within the pressure chamber of a level such that liquid is not ejected from the nozzle; a minimum electric potential of the micro-oscillating activation pulse is no greater than a maximum electric potential of the ejection activation pulse; and the ejection activation pulse is supplied to a piezoelectric element corresponding to an ejecting nozzle ejecting ink in a unit cycle, and the micro-oscillating activation pulse is at least supplied to a piezoelectric element corresponding to a non-ejecting nozzle located adjacent to the ejecting nozzle.
