Abstract
A simple and high productivity liquid filling method is provided for a small-size liquid container having a high efficiency of use in which an amount of accommodated ink per unit volume is increased and a stable liquid supply can be realized. This method fills a liquid into a liquid container, which includes a first chamber incorporating a negative pressure Generating member and including a liquid supply portion and an atmospheric-air communicating portion, and a second chamber including a communicating portion communicating with the first chamber and forming a substantially closed space. The method includes the step of prohibiting discharge of air within one of the first chamber and the second chamber, and simultaneously filling a liquid into the other chamber while discharging air within the other chamber to the outside of the liquid container, in a state in which the communicating portion is placed at a lower position in a direction of gravity.
