PROBLEM TO BE SOLVED: To provide a liquid jetting apparatus which can perform good printing by removing air bubbles generated in a liquid feeding passage which connects a liquid storing body and a liquid jetting head each other. SOLUTION: A CPU acquires temperature data which show a temperature of a using environment detected by a temperature sensor, and time data which show a rest time of jetting measured by a timer (steps S10 and S11). The CPU judges from the temperature data and time data whether or not air bubbles are generated in an ink feeding tube which connects an ink cartridge and a recording head each other (step S13). When the judgment result is affirmative, the CPU makes the cleaning operation carried out to recover the capability of jetting the ink of the recording head (step S15).
