Abstract: A CONTAINER FOR CONTAINING LIQUID TO BE EJECTED.THE CONTAINER INCLUDES A NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER FOR ACCOMMODATING A NEGATIVE PRESSURE PRODUCING MEMBER. THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER IS PROVIDED WITH AN AIR VENT FOR FLUID COMMUNICATION WITH AMBIENCE AND A LIQUID SUPPLY PORTION FOR SUPPLYING THE LIQUID TO A LIQUID EJECTING HEAD HAVING EJECTION OUTLETS. THE CONTAINER ALSO INCLUDES A LIQUID CONTAINING CHAMBER WHICH IS SUBSTANTIALLY HERMETICALLY SEALED EXCEPT FOR A FLUID COMMUNICATION PATH THROUGH WHICH THE LIQUID CONTAINING CHAMBER IS IN FLUID COMMUNICATION WITH THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER. A PARTITION IS PROVIDED FOR SEPARATING THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER AND THE LIQUID CONTAINING CHAMBER. THE PARTITION IS PROVIDED WITH AN AMBIENCE INTRODUCTION PATH FOR INTRODUCING THE AMBIENCE INTO THE LIQUID CONTAINING CHAMBER FROM THE NEGATIVE PRESSURE PRODUCING MEMBER ACCOMMODATING CHAMBER. THE AMBIENCE INTRODUCTION PATH FORMS A CAPILLARY FORCE GENERATING PORTION. THE CAPILLARY FORCE WHICH IS PRODUCED BY THE CAPILLARY FORCE GENERATING PORTION SATISFIES A RELATIONSHIP BETWEEN THAT CAPILLARY FORCE AND POTENTIAL HEAD DIFFERENCES, HEAD LOSSES, AND OTHER CAPILLARY FORCES IN THE CONTAINER.(FIG 1)

Abstract: An adsorbent (101) for ink jet use arranged in a position to be in contact with ink, having the higher capability of adsorption with respect to hydrophobic substance contained in ink than colorant therein. Then, an ink retaining container (100) comprises an ink retaining portion for retaining ink to be supplied to an ink jet head, an ink supply opening which becomes the ink supply portion from the ink retaining portion to the head, an atmospheric communication opening for communicating the ink retaining portion with the air outside. This ink retaining container is provided with the above-mentioned adsorption member arranged in a position to be in contact with ink in it. With the adsorbent and the ink retaining container thus arranged, it is made possible to perform ink jet recording with excellent print characteristics by effectively removing the hydrophobic substance eluted form the ink absorbent in the ink retaining container.
