An ink cartridge for use with a recording apparatus, wherein the ink cartridge is removablymountable to the recording apparatus and comprises a circuit board. The circuit board has data-readable storage means in which ink information canbe stored and a connect ion terminal electrically connectable to a terminal mechanism arranged on the recording apparatus. The circuit board is attached to a cartridge case of the ink cartridge within a box-shaped space having two opened surfaces which intersect each other at right angles. The connection terminal is exposed toward one of the two opened surfaces. In a state where the ink cartridge is mounted to the recording apparatus, the connection terminal is electrically connected to the terminal mechanism on the recording apparatus through the other one of the two opened surfaces.

A valve unit 36 is placed in an ink flow passage 35 between an ink cartridge 8 and a recording head 7 and can be controlled in association with the cleaning operation of the recording head 7. Under the control of a drive controller, the valve unit 36 holds for a predetermined time a state in which negative pressure produced by a suction pump is accumulated, and is opened after the expiration of the predetermined time or is opened with the negative pressure accumulated and driving the suction pump is continued. The air bubbles remaining in a stuck state in the ink flow passage can be peeled from the ink flow passage together with an instantaneous fast ink flow produced as the valve unit 36 is opened, and the peeled air bubbles can be discharged effectively from the ink flow passage following the subsequent ink flow.

A circuit board on an ink cartridge has contact pads which are electrically conducted to a semiconductor storage element mounted on the circuit board. Connector terminals on an ink jet recording apparatus are brought into relative slide contact with a surface of this circuit board, and electrically connected to the contact pads. When the connector terminals come in contact with the contact pads, the dust adhering to the connector terminals is wiped and removed by step portions that are constituted by no-resist-film formation parts and that are adjacent to the contact pads. Consequently, the reliability of the electrical contact between the connector terminals and the contact pads is ensured.
a sub-tank unit (4) provided with a record head (5); and a main tank capable of replenishing said sub-tank unit (4) with ink, wherein an ink storage chamber (25) and the record head (5) of said sub-tank unit (4) are connected through backflow prevention valve (26,27,28) for enabling ink to flow into the record head (5) from the ink storage chamber (25), and wherein an ink replenishment unit (8) for replenishing said sub-tank unit (4) with ink from the main tank by reducing pressure in the ink storage chamber by negative pressure generation means is provided.
