Abstract:
1. A liquid droplet ejecting device comprising: a liquid droplet ejecting head that ejects a liquid droplet from a nozzle; a liquid storage unit that stores a liquid to be supplied to the liquid droplet ejecting head; a first flow path that connects the liquid droplet ejecting head and the liquid storage unit; a second flow path that connects the liquid droplet ejecting head and the liquid storage unit, and connects with the first flow path in the liquid droplet ejecting head; the first flow path and the second flow path being different paths between the liquid droplet ejection head and the liquid storage unit; a bypass flow path that is connected with the first flow path and the second flow path; a liquid feed unit that is provided between the liquid storage unit and a connecting portion of the bypass flow path and the first flow path, and that circulates the liquid in the liquid droplet ejecting head and the liquid storage unit; and a pressure control unit that is provided at the bypass flow path, and controls pressure of the liquid flowing through the bypass flow path from the first flow path side to the second flow path side.
