    • An ink cartridge is described which is connectable to an ink jet recording head of an ink jet recording apparatus. The cartridge is generally formed by a front wall, a back wall, a top wall, a bottom wall and two side walls providing major inner surfaces of the cartridge. The cartridge includes a first chamber and a second chamber. The first chamber contains negative pressure producing material and has an ink outlet connectable to the ink jet head to supply ink from the cartridge to the ink jet head and an air vent for allowing air into the cartridge. The second chamber has a communication port adjacent to the bottom wall, and communicates with the first chamber through the communication port. The second chamber provides an ink reservoir for the first chamber. Inner corner portions, formed by intersection of the inner side of the side walls adjacent to the communication port and the bottom wall, and which extend toward the communication port, are rounded.
