A liquid droplet ejecting device (200) that includes multiple pressure chambers (27) communicating with multiple nozzles (20), to contain liquid; a vibration plate (30), to constitute elastic walls of the pressure chambers, disposed extending along the pressure chambers; multiple pressure generating elements (35) disposed facing the multiple chambers respectively via the vibration plate; a drive waveform generator (212) to generate drive waveform data that indicates a shape of a drive waveform for driving the multiple pressure generating elements; a residual vibration detector (240) to detect a residual vibration waveform occurring within the pressure chamber after the pressure generating elements are driven; and a controller (211) to determine the necessity of liquid-state recovery ejection for discharging thickened liquid, based on the detected residual vibration, and to cause the liquid-state recovery ejection to be performed upon determining that liquid-state recovery ejection is needed. |
