LIQUID SUPPLY METHOD, LIQUID SUPPLY CONTAINER, NEGATIVE PRESSURE GENERATING MEMBER STORING CONTAINER, AND LIQUID STORING CONTAINER

摘要

PURPOSE: To prevent stagnation or accumulation of bubbles in a communicating part. CONSTITUTION: The upper wall surface 122 of a joint pipe 180 for communicating a negative pressure controlling room container 110 and an ink storing container 201 is tilted upward from the negative pressure controlling room container 110 to the ink storing container 201. Since the upper wall surface 122 of the joint pipe 180 is tilted, flow into the ink storing container 201 can be enabled without stagnation or accumulation of bubbles on the upper wall surface 122 of the joint pipe 180 at the time of gas-liquid exchange.
