Abstract
To prevent leakage of ink in an ink tank from an air inflow port formed in an ink cartridge, an accommodating section in which an ink absorbing member is disposed is provided outside the ink cartridge so that the ink absorbing member opposes the air inflow port of the ink cartridge. The accommodating section is fluidly connected to the air inflow port of the ink cartridge and formed with an atmosphere communication hole in communication with atmosphere. Thus, ink leaked out through the air inflow port can be absorbed by the ink absorbing member and air can be introduced into the ink tank for an amount corresponding to an amount of ink supplied to a recording head.
