It is described an ink cartridge using an ink bag (20) capable of being mounted in a carriage, comprising: a container having a body unit (1) and a cover unit (3) to form an internal space therebetween, at least one of said body unit (1) and said cover unit (3) being provided with valves (10, 11) openable for communication between the internal space of said container and the atmosphere according to pressure change in said container; a cap (21) connecting with an ink supply needle (30) of a recording head mounted in a carriage; and an ink bag (20), the periphery (20a) of which is held by said cover unit (3) and body unit (1). A constant negative pressure can be maintained by valves (10, 11), and the periphery of ink bag (20) is held by body unit (1) and cover unit (3), ensuring as constant a shape as possible and preventing pressure changes caused by oscillation. <IMAGE>
