Ink jet recording apparatus

An ink jet recording apparatus comprising:

• a recording head that ejects ink;
• an ink tank including an ink storage chamber configured to store ink, an air storage chamber configured to communicate with atmosphere, and a connection path configured to connect the ink storage chamber and the air storage chamber;
• an ink supply path that connects the connection path and the recording head;
• a valve provided on the connection path and configured to be switched between an open state in which the ink storage chamber communicates with the ink supply path and with the air storage chamber, and a close state in which the communication between the ink storage chamber and the ink supply path is blocked and the communication between the ink storage chamber and the air storage chamber is blocked, the valve does not block a communication between the ink supply path and the air storage chamber;
• a valve shaft that switches the valve between the open state and the close state;
• and
• an ink suction mechanism to perform an ink suction operation with the valve being in the close state for sucking ink from the recording head, the ink supply path and the air storage chamber.
