Abstract

A recording head (17a to 17c) includes an ink ejection portion (41) having a plurality of ejection nozzles (18) for ejecting ink and an ink reservoir (43) coupled to the ink ejection portion (41). The ink reservoir (43) includes an in-head flow passage (46) coupled to a common flow passage (40) for circulating ink, an air bubble separation portion (47) that separates air bubbles contained in ink flowing through the in-head flow passage (46), a valve member (50) that opens and closes an air bubble discharge port (47b) formed in a top part of the air bubble separation portion (47), and an ink discharge flow passage (48) extending downward from an ink inflow port (47a) formed in a lower end part of the air bubble separation portion (47) and coupled to the ejection nozzles (18) in the ink ejection portion (41). The in-head flow passage (46) is coupled substantially horizontally to the ink discharge flow passage (48) and a junction portion (52) between the in-head and the ink discharge flow passages (46, 48) is below the ink inflow port (47a).
