Abstract
A liquid droplet ejecting apparatus is provided. The liquid droplet ejecting apparatus includes: a liquid storage container for storing a liquid therein; a carriage configured to reciprocate; an ejecting head mounted on the carriage and configured to eject liquid droplets; a liquid tank which is mounted on the carriage and is connected to the ejecting head and which is connected to the liquid storage container via a flexible tube; an air supply and discharge unit configured to supply air to the liquid tank and discharge air from the liquid tank; and a pressure controller controls the air supply and discharge unit so as to reduce a pressure fluctuation in the internal pressure of the liquid tank generated due to an inertial force applied to a liquid in the tube when the carriage changes a moving direction thereof.
