Abstract

An ink jet unit includes an ink jet head for ejecting ink; an ink cartridge for containing ink to be supplied to the ink jet head; an ink supply member for introducing the ink from the ink cartridge, provided in the ink jet head; a negative pressure generating material in the ink cartridge; an opening for permitting contact between the negative pressure generating material and in the ink supply member; wherein a gap is formed in the opening when the ink supply member is in contact with the negative pressure generating material. <IMAGE>
