ABSTRACT:
A container for containing printing liquid for supplying to an ink jet head for an ink jet recording apparatus. The container includes first and second chambers, with the first chamber containing negative pressure producing material and having an air vent communicating with ambient air and a supply port for supplying printing liquid to the ink jet head. The second chamber communicates with the first chamber via a communication port and provides a printing liquid reservoir for the first chamber. In an area adjacent a wall extending from the communication port, a capillary force provided by the negative pressure producing material decreases in a direction perpendicular to and towards that wall at least adjacent a part of the communication port which is uppermost when the container is in use.
