An ink cartridge includes a case, an ink supply portion positioned at a front face of the case, a movable member configured to move relative to the case, and at least one resilient member coupled to a rear face of the case and the movable member. The at least one resilient member is configured to expand in an expansion direction and to contract in a contraction direction to move the movable member relative to the case, and a shape of the case in the expansion and contraction directions is unaltered. The entire moveable member is configured to substantially simultaneously move relative to the case when the at least one resilient member expands and contracts.
