There is provided a liquid droplet jetting apparatus, including: a liquid droplet jetting head in which a plurality of nozzles and a plurality of individual channels are formed; a purge mechanism; a judgment mechanism which judges whether or not a defective nozzle in which a jetting failure occurs is included in purge target nozzles; a heating mechanism which heats a liquid in the plurality of individual channels; and a controller which controls the purge mechanism and the heating mechanism. In a case that the judgment mechanism judges that the defective nozzle is included in the purge target nozzles, the controller controls the heating mechanism and the purge mechanism to heat the liquid in a part of the plurality of individual channels, which include an individual channel communicating with the defective nozzle, and to execute the purge operation for the purge target nozzles.
