Abstract
There is provided a liquid droplet forming apparatus comprising: a liquid holding part configured to hold a liquid including precipitating particles; a film member configured to be vibrated so as to eject the liquid held in the liquid holding unit, wherein a nozzle is formed in the film member and the liquid is ejected as a droplet from the nozzle; a vibrating unit configured to vibrate the film member; and a driving unit configured to selectively apply an ejection waveform and a stirring waveform to the vibrating unit, wherein the film member is vibrated to form the droplet in response to applying the ejection waveform and the film member is vibrated without forming the droplet in response to applying the stirring waveform.
