Abstract
A pressure buffer of an ink-jet recording apparatus is placed in the vicinity of an ink-jet recording head in an ink supply path connecting an ink container to the ink-jet recording head. A body of the pressure buffer has a concave portion at least on one surface, and a flexible film is attached to tightly close the concave portion to form a chamber. The chamber has an ink flow outlet through which ink flows from the chamber to the ink-jet recording head and an ink flow inlet through which ink flows from the ink container to the chamber. The ink flow outlet is always positioned in an uppermost portion in a vertical direction of the chamber, and the ink flow inlet is positioned at an equal level or on a lower side in a vertical direction with respect to the ink flow outlet.
