A liquid ejection apparatus comprises a liquid cartridge for storing a liquid, a liquid ejection head for ejecting the liquid toward a target, a liquid supply path for guiding the liquid to the liquid ejection head from the liquid cartridge, and a capping device for drawing the liquid from the liquid ejection head. The liquid supply path comprises a plurality of wall surfaces, and a part of the wall surface is formed of a flexible member that is flexed by the inside-and-outside pressure difference of the liquid supply path. A pressure pump for adjusting the pressure of a fluid within the liquid supply path in the upstream side of the flexible member is provided.
