An ink jet cartridge has a recording head portion and an ink containing portion which are detachably mountable relative to each other. The recording head portion ejects ink to effect recording with the ink. The cartridge includes a first ink container, provided in the recording head portion, for containing the ink; a second ink container, provided in the ink containing portion, for containing the ink; and an ink communication tube for establishing ink communication between the first ink container and the second ink container, wherein the ink communication tube is not externally exposed. An ink jet recording apparatus includes a recording head for ejecting ink, an ink container detachably mountable to the recording head for containing the ink to be supplied to the recording head, a detecting device for detecting mounting of the ink container to the ink jet recording apparatus and a control device for controlling a recording operation of the ink jet recording apparatus in accordance with an output of the detecting device.

An ink tank for storing ink to be supplied to a recording unit comprises a bag-like member arranged in an inner space of the ink tank and communicating with the atmosphere, which bag-like member has a volume variable from substantially zero to a volume substantially equal to that of the inner space of the ink tank. Ink is stored in a space defined between the ink tank and the bag-like member and a liquid path is formed in an inner wall surface of the ink tank.

An ink jet cartridge is composed integrally of a recording head and an ink tank, which are constructed in mutually separable manner, in order to enable repeated use of the recording head by replacement of the ink tank. In an ink supply part in the ink tank, an elastic partition wall is provided with a slit which is normally closed but is opened under a predetermined pressure difference. The slit is so designed as to generate an appropriate negative pressure on the recording head, thereby preventing ink leakage. Also a slit shielding valve member is provided to shield the slit at the abrupt inhaling action of the ink tank at the detaching of the ink tank, in order to prevent air intrusion into the ink tank.

An ink storage unit used in an ink jet recording apparatus for recording by ejecting ink comprises a plurality of ink storage chambers, a plurality of movable walls and a mechanism for holding each of the movable walls. Each of the ink storage chambers stores ink. Each of the movable walls is provided in the each ink storage chamber respectively so as to seal stored ink against air, and each movable wall can move according to a change of amount of ink in each ink storage chamber. The mechanism for holding the movable walls exerts a force opposed to a force which is exerted on the each movable wall according to the change of amount of ink, on each of the movable walls so as to make the pressure in each ink storage chamber an appropriate negative pressure.
