A liquid droplet jetting apparatus is capable of carrying out selectively a first purge mode and a second purge mode. In the first purge mode, a first air discharge purge of discharging air in an ink storage chamber is carried out while maintaining a meniscus of the ink. In the second purge mode, a second air discharge purge of discharging air inside the ink storage chamber is carried out while destroying the meniscus of the ink. Accordingly, there is provided a liquid droplet jetting apparatus in which it is possible to discharge a gas inside a liquid supply channel from an upstream side of the nozzle, and also, when the degree of thickening of the liquid inside the nozzle is extreme, it is possible to discharge the thickened liquid assuredly from the nozzle.
