Abstract
An ink jet recording apparatus includes an ink jet head having a pressure chamber opposed to a nozzle, an upstream port that communicates with the pressure chamber, and a downstream port, a first tank that communicates with the ink jet head via the downstream port and is capable of storing an ink, a second tank that communicates with the first tank and is capable of storing the ink, a third tank that communicates with the ink jet head via the upstream port and communicates with the second tank and is capable of storing the ink, an opening and closing mechanism that is capable of opening and closing a circulation path that connects the ink jet head, the first tank, the second tank, and the third tank, and an air pressure adjusting mechanism that is capable of adjusting an internal air pressure in at least one of the first tank, the second tank, and the third tank. The ink is fed through the circulation path according to an air pressure generated by adjustment of the air pressure and an opening and closing state of the circulation path.
