An ink tank cartridge for an ink-jet type recording apparatus being removably mountable onto an ink supply needle of said ink jet type recording apparatus is provided. The ink tank cartridge comprises a first chamber for storing ink and a second chamber for storing a porous member. A partition wall separates the first chamber from the second chamber. A lid is attached to the top of the cartridge and at least a portion of the lid corresponding to at least one of the chambers may be opened to allow for replenishment of ink in the ink tank cartridge. Alternatively, the lid may be permanently fixed to the top on the ink tank cartridge, and an ink replenishment hole may be formed in the lid to allow for replenishment with an ink injection device. The ink tank may also be replenished by placing a self contained ink replenishment pack into said ink tank cartridge.
