ABSTRACT:
A liquid-droplet ejecting apparatus including a liquid ejecting head having an ejection opening from which a droplet of a liquid is ejected, a first tank in which a liquid storing chamber storing the liquid to be supplied to the liquid ejecting head and a gas chamber storing a gas are formed, a second tank storing the liquid to be supplied to the liquid storing chamber, a gas-permeable film which closes a communication portion at which the gas chamber and liquid storing chamber communicate with each other, separates the gas chamber and liquid storing chamber from each other, and allows the gas to pass therethrough but does not allow the liquid to pass therethrough, a suction passage in communication with the gas chamber, a sucking device sucking the gas from the gas chamber through the suction passage, and a pressure control device disposed in the suction passage and communicating an internal space of the suction passage with an external space of the suction passage when an internal pressure of the suction passage decreases below a threshold lower than the atmospheric pressure due to the sucking of the gas by the sucking device, in order to inhibit the internal pressure of the suction passage from excessively decreasing.
