ABSTRACT:
An ink cartridge includes a cartridge case having a partition in it, which partitions its interior into an ink chamber and a storage chamber. The ink chamber contains ink, and the storage chamber contains a member impregnated with ink. The partition has an ink passage formed through it. The relationship between the width "w" of the passage and the width "d" of the storage chamber meets the expression w.ltoreq.d/2. Even if gaps remain along edges of the storage chamber around the member, air bubbles are restrained from flowing from the gaps through the passage into the ink chamber.
