Abstract
A replaceable ink cartridge has a body for storing the ink; an ink outlet for supplying the ink into a recording head; an air communicating port for communicating with an atmosphere; a peripheral portion around the ink outlet; a peripheral portion around the air communicating port; a seal member for removably sealing the peripheral portion around the ink cutlet and the peripheral portion around the air communicating port. The replaceable ink cartridge has a structure that is formed so as to strip the seal member off from the peripheral portions of the ink outlet and the air communicating port in a manner that the air communicating port is opened at first and the ink outlet is opened at second.
