ABSTRACT:
An ink supply system in which gas is promptly and smoothly discharged without having a complex structure. The ink supply system includes a hermetically-sealed structure communicating with a liquid-using section, a liquid accommodating section having a liquid storage adapted to store liquid, the liquid accomodating section including a negative pressure generation means, and a plurality of communication paths, including first and second communication paths, that facilitates communication between the liquid chamber and the liquid accommodating section. Each of the first and second communication paths includes a liquid chamber side opening extending into the liquid chamber and a liquid accommodating section side opening extending into the liquid accommodating section. The liquid chamber side opening of the first communication path extends substantially further into the liquid chamber than the liquid chamber side opening of the second communication path, and the liquid accommodating section side opening of the second communication path extends substantially further into the liquid accommodating section than the liquid accommodating section side opening of the first communication path.
