A liquid-droplet ejecting apparatus including: (a) a liquid ejecting head having an ejection opening from which a droplet of a liquid is ejected; (b) a liquid supply passage through which the liquid is supplied to the liquid ejecting head; (c) a suction passage normally held in communication with the liquid supply passage; (d) a sucking device sucking a gas in the liquid supply passage via the suction passage; (e) a gas-permeable film disposed at a communication portion at which the liquid supply passage and the suction passage are communicated with each other, the gas-permeable film allowing the gas to pass therethrough but not allowing the liquid to pass therethrough; (d) an opening-and-closing device selectively placeable in a closed state to disconnect the suction passage from the sucking device, and an open state to communicate the suction passage with the sucking device; (e) a pressure detecting device detecting an internal pressure of the suction passage; (f) a sucking-device control device controlling the sucking device; the opening-and-closing device being placed in the open state when the sucking device is to suck the gas from the suction passage, and being placed in the closed state when the sucking device completes the sucking of the gas from the suction passage; and the sucking-device control device having the sucking device suck the gas in the liquid supply passage when the pressure detecting device detects that the internal pressure is equal to or above a predetermined threshold.
