PURPOSE:To eliminate leakage of ink from an ink guide or an ink discharge port at the time of handling with a sole unit even if an ink retaining performance is low and cope with high speed of recording in an ink tank detachable to an ink jet recorder or an ink tank integrated with a recording head. CONSTITUTION:A unit having a valve 1340 for opening an atmospheric communication hole 1322 via a shaft 510 at the time of mounting at an ink jet recorder or checking it at the time of non-mounting is provided in an ink tank. Thus, ink retaining performance in the tank is reduced without considering leakage of ink at the time of non-mounting at the recorder, and an ink cartridge for rapidly refilling ink in an ink discharge port is performed. As a result, recording can be accelerated. |
