A droplet ejecting device includes an ejector that is adapted to eject a liquid stored in a pressure chamber from an ejecting nozzle, by applying pressure to the pressure chamber; an ejection timing detector that is adapted to detect a start timing at which a liquid column starts being ejected from the ejecting nozzle; a droplet separator that is adapted to give, to the liquid column, an energy that separates the liquid column from the liquid stored in the pressure chamber; and a controller that is adapted to control the droplet separator to give an energy at a timing when a predetermined time period has elapsed since the start timing detected by the ejection timing detector.
