A liquid cartridge comprising:
- a liquid chamber;
- a liquid supply portion providing selective liquid communication between an interior of the liquid chamber and an exterior of the liquid chamber;
- a partitioning wall partitioning the liquid chamber into a first liquid chamber and a second liquid chamber;
- a communication path providing selective liquid communication between the first liquid chamber and the second liquid chamber;
- a blocking member having a block position in which liquid is prevented from flowing from the first liquid chamber to the second liquid chamber through the communication path, such that liquid is stored in the first liquid chamber and not stored in the second liquid chamber, wherein the liquid has a first specific gravity;
- and
- a first movable member positioned in the second liquid chamber and comprising a float, wherein the float has a second specific gravity which is less than the first specific gravity, and the float moves in response to the level of liquid in the second chamber when liquid flows from the first liquid chamber to the second liquid chamber.
