Abstract
A liquid cartridge includes: a liquid container including a liquid storage chamber; a liquid supply portion including a liquid supply chamber and first and second openings; a movable member; a sealing member; and a connecting channel. The first opening provides communication between the supply chamber and an exterior of the cartridge. The second opening provides communication between the supply chamber and the storage chamber. The movable member extends in the storage chamber and the supply chamber. The sealing member intimately contacts the movable member and the liquid supply portion continuously in a circumferential direction. The connecting channel is formed in the movable member and provides communication between a space in the supply chamber and the storage chamber so that liquid can flow therebetween. The connecting channel opens into the storage chamber at a position further downward than the second opening when the cartridge is in an attached posture.
