PURPOSE:To improve the use efficiency of a recording liquid to accomplish a small-sized container by a method wherein an ink is suctionally removed so that an amount of ink held in an area of a porous body only on the side of an air communicating port is smaller than that held in an area of an ink discharge part. CONSTITUTION:The pressure in an ink tank is reduced, and an ink is injected from a supply port 1200 so as to fill all through the ink tank. In this manner, a porous member 902 can be fully charged with the ink. A suck-out port 1401 is opened with the supply port closed, and the excess of the ink over a predetermined recording liquid injection amount is sucked out from the suck-out port. A gap between the supply port 1200 and the suck-out port 1401 is determined to be as proximate to a maximum dimension in a liquid jet recording head as possible and desirably meets a relation of (l1/l2)=0.7. In this manner, the recording liquid is distributed to be concentrated on the side of the supply port, whereby the ratio of a suppliable ink amount to an injected ink amount is raised to approximately 80% or more.
