Abstract

A liquid droplet ejecting apparatus includes: a supply-use tank that is sectioned by an elastic film into a liquid chamber and a gas chamber; a supply-use flow path that interconnects the supply-use tank and a recording head; and a pump that pumps the liquid stored in the liquid chamber to the recording head via the supply-use flow path by supplying the liquid from an external tank to the liquid chamber of the supply-use tank. The flow path is controlled to supply the liquid to the liquid chamber in a state where the supply-use flow path is closed, cause the elastic film to press against an inner wall of the gas chamber, thereafter open the supply-use flow path, release the elastic film from the pressing state, and supply, with the pump, the liquid from the external tank to the recording head via the supply-use tank and the supply-use flow path.
