Claim:
A liquid container comprising: a liquid containing portion for containing ink; a liquid introduction portion for introducing liquid from an outside into an inside of said liquid containing portion; a liquid discharge portion for discharging the liquid from the inside of said liquid containing portion to an outside of said liquid containing portion; a gas-liquid separating member provided in an upper side, in use, of said liquid containing portion, said gas-liquid separating member including a gas-liquid separation film and a blocking portion in which said gas-liquid separation film is disposed, wherein said blocking portion does not pass gas or liquid, and wherein a space region is provided below said gas-liquid separating member; wherein a pressure in said container is reduced through said gas-liquid separation film to discharge the gas from the inside of said liquid containing portion to the outside of said liquid containing portion so that liquid is introduced into said liquid containing portion through said liquid introduction portion, wherein said one or both of said gas-liquid separating member and said gas-liquid separation film has a portion which is inclined relative to a side of said liquid containing portion such that a contact line provided by contact between a gas-liquid interface between the introduced liquid and the gas and said gas-liquid separation film moves toward a boundary between said gas-liquid separation film and said blocking portion, and wherein introduction of the liquid is completed with a state in which the gas-liquid interface between the liquid and the gas reaches the boundary between said gas-liquid separation film and said blocking portion, and in the state in which gas is in a region which is below said blocking portion which takes an upper position in use.
