Abstract
By solving the problem of unstable ink supply which occurs due to bubble stagnation in a communication portion at a high ink supply rate per unit time when a fiber absorbent is used as a negative pressure generating member in the ink tank or ink supply system in which a negative pressure generating member container is adjacent to a liquid container, the present invention provides an ink tank and a liquid supply system which supply ink stably.
