    摘要: A liquid ejection apparatus (1000) includes a liquid storing unit (2001) capable of storing liquid, a liquid ejection unit (10) including an ejection port (103) that is capable of ejecting the liquid, and a pressure control unit (202) that receives the liquid from the liquid storing unit (2001) and allows the liquid having a pressure controlled to be within a predetermined pressure range to be supplied to the liquid ejection unit (10). Additionally, the liquid ejection apparatus (1000) includes a first circulation unit that supplies the liquid having the pressure controlled by the pressure control unit (202) to the ejection port (103) while circulating the liquid between the liquid ejection unit (10) and the pressure control unit (202), and a second circulation unit that circulates the liquid between the liquid storing unit (2001) and the pressure control unit (202).
