ABSTRACT:
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.
