ABSTRACT:
In a sealing member of an ink feed connecting member, an ink sealing section surrounds at least a part of an ink guide when an ink cartridge is not attached to the ink feed connecting member. The ink sealing member is disposed such that an opening of the ink sealing section is opposite to an ink feed port. The circumferential edge of the ink sealing member is invertedly deformed as the ink cartridge is attached to the ink feed connecting member. When the ink cartridge is fully attached to the ink feed connecting member, the ink sealing section enters the ink cartridge while an inner circumferential edge of the ink sealing member is in contact with an inner peripheral surface of the ink feed port. The surface of the inverted circumferential edge seals the inner peripheral surface of the ink feed port.
