Abstract
For the sake of achieving both the size and weight reductions of a printing apparatus and increasing the reliability thereof, an ink tank is provided with a gas-permeable member that permits air to pass without permitting ink. The ink tank is capable of introducing ink through an ink inlet by negative pressure introduced in the ink tank through a common suction port.
