An ink tank cartridge for an ink-jet type recording apparatus is provided. The ink tank cartridge comprises a plural number of first chambers and a plural number of second chambers adjacent to and associated with a first chamber, each pair of first and second chambers being formed as an integral unit. The ink tank cartridge also has a partition wall disposed in the cartridge which separates each second chamber from an associated first chamber, the two chambers communicating through a communicating hole positioned near the bottom of the partition wall disposed between the associated chambers. The communicating hole extends only a portion of the width that the partition wall. Finally, a plural number of ink supply ports, each extending through a wall of a respective one of the plural number of first chambers, supply ink to the exterior of the ink cartridge from each respective porous member of the plural number of porous members.
