In a construction in which between ink supply parts (38B to 38Y) and a second chamber (30B) of ink tanks (8B to 8Y) is selectively connected through a tube (44), a needle (31B) and septum (34B), ink IN stored in the ink supply parts (38B to 38Y) is supplied to the second chamber (30B) of the ink tanks (8B to 8Y) by a pump (40), and then, a part of ink of the second chamber (30B) of the ink tanks (8B to 8Y) is supplied to the ink supply parts (38B to 38Y), thereby introducing an air from the first chamber (30A) to the second chamber (30B) through the communicating passage (30T).
