Abstract
There is disclosed a liquid supply method in which a bubble is prevented from being retained or accumulated in a communication part. An upper wall surface of a joint pipe for connecting a negative pressure control chamber container to an ink container is inclined upward to the ink container from the negative pressure control chamber container. Since the upper wall surface of the joint pipe is inclined, the bubble flows into the ink container without being retained or accumulated on the upper wall surface of the joint pipe during gas-liquid exchange.
