摘要： A liquid ejection apparatus includes: a storage chamber which is connectable to a cartridge storing liquid and stores liquid supplied from the cartridge; a movable member provided in the storage chamber and including a float and a detection target portion, the float being lower in specific gravity than the liquid stored in the storage chamber; and a detection unit which detects movement of the movable member by detecting the detection target portion. The detection target portion is movable from a first position to a third position through a second position. The detection unit is arranged to detect the detection target portion in a case where the detection target portion is present at the second position.
