Abstract
An ink tank cartridge (A) includes a housing (10) having a bottom wall (28) and a plurality of side walls (12, 14, 16, 18) forming a cavity (20). A divider wall (22) is positioned within the cavity to divide the cavity into first and second chambers (24, 26). An ink supply port (42) projects from the bottom wall of the housing. A porous member (40) is accommodated in the chamber having the ink supply port. The other chamber is partially filled with ink. The divider wall has an opening (30) allowing ink to pass from one of the chambers to the other chamber. A cover (50) having a fill hole (94) is secured to the housing.
