An ink container contains main tanks into which ink can be poured from the outside and the ink in the main tanks is supplied to recording heads via deaerators incorporating hollow fibers to which negative pressure is applied from the outside. The ink in the ink tanks is deaerated by the deaerators before an ink-end condition is brought on and then supplied to the recording heads.
