Abstract
Provided is a liquid storage container that allows for a simplified structure and a reduction in the size and the cost of a printing apparatus. To this end, the liquid storage container includes: two liquid chambers partitioned from each other; a flow path through which liquid can move between the liquid chambers; a valve configured to open and close the flow path; a refilling port that is configured to be opened and closed and through which a liquid chamber can be refilled with the liquid; and a pressure adjustment mechanism that is provided in a liquid chamber configured not to be refilled with the liquid through the refilling port and that adjusts a pressure in the printing head.
