A droplet ejecting apparatus includes a liquid filling chamber filled with a liquid, and a plurality of pressure chambers in communication with the liquid filling chamber and filled with the liquid. Each of the pressure chambers includes a communication port in communication with the liquid filling chamber, a pressure generating element for exerting pressure on the liquid which fills the interior of each pressure chamber, and a nozzle for ejecting the liquid in each pressure chamber therefrom in the form of droplets. A recovery controller brings the pressure generating element corresponding to the communication port included in a partial region of the liquid filling chamber into operation to cause the corresponding nozzle to eject the droplets. This produces a flow of the liquid directed toward the partial region in the liquid filling chamber to efficiently diffuse precipitable ingredients accumulating in the liquid filling chamber, thereby efficiently eliminating the accumulation of the precipitable ingredients in the liquid filling chamber in communication with the pressure chambers. |
