An ink-cartridge for printers and an ink refilling method are provided to maintain constant cartridge pressure with enlarging internal space of an ink-cartridge by removing sponge inside the ink-cartridge. An ink-cartridge for printers includes refilling chambers, a discharge chamber, an ink discharge hole(17), an ink flow groove(24), an air chamber(27), an air guide groove(30), a shielding film(42), a cover(50), and a pressure controller(40). The refilling chambers are partitioned by separators having a connection groove inside the body. The discharge chamber is connected with the refilling chambers. The ink discharge hole discharges ink. The ink flow groove connects the discharge chamber and the ink discharge hole, including a bubble collecting part(26). The air chamber is connected with the refilling chamber by the medium of an air flow groove for supplying air to the refilling chamber. The air guide groove guides external air into an air suction valve. The shielding film is attached to a side of the body. The cover is installed on the other side of the body. The pressure controller is formed on a part of exterior of the body and is connected with the refilling chamber.
