PROBLEM TO BE SOLVED: To deter the air from flowing into an ink channel when filled with the ink. SOLUTION: The valve 50 is connected to a reservoir unit which has the ink channel formed inside. The valve 50 has: a valve chamber 56 which includes an ink supply port 56a through which the ink is supplied, an outside ejection port 56b through which the ink is ejected to the outside, and a reservoir ejection port 56c through which the ink is ejected to the ink channel; and a valve top 52 which includes a sealing member 62. The valve top 52 can selectively take either of a position where the sealing member 62 opens the outside ejection port 56b while sealing the reservoir ejection port 56c, and a position where the sealing member 62 opens the reservoir ejection port 56c while sealing the outside ejection port 56b.
