Abstract:
A liquid droplet ejecting method for ejecting a liquid from at least one ejection hole to form the liquid into liquid droplets, the method including: applying a vibration to the liquid in a liquid column resonance-generating liquid chamber, in which the ejection hole is formed, to form a standing wave through liquid column resonance, and ejecting the liquid from the ejection hole, which is formed in a region corresponding to an antinode of the standing wave, to form the liquid into liquid droplets.
