Ink tank, ink-jet cartridge, ink supplying apparatus, ink-jet printing apparatus and method for supplying ink

摘要

For the sake of achieving both size and weight reductions of a printing apparatus and increasing the reliability thereof, an ink tank (20) is provided with a gas-permeable member (48) that permits air to pass without permitting ink. The ink tank (20) is capable of introducing ink through an ink inlet (20b) by negative pressure introduced in the ink tank (20) through a common suction port (53).
