Abstract
A liquid ejection apparatus includes an ejection head that ejects a liquid, a container that stores the liquid, and a reservoir that supplies the liquid to the ejection head and stores the liquid supplied from the container. The reservoir includes a first chamber that stores the liquid, a second chamber that is arranged downstream of the first chamber and stores the liquid, and a first flow path and a second flow path that communicate the first and second chambers with each other. A communication port between the first chamber and the second flow path is located lower than a communication port between the first chamber and the first flow path in a usage posture of the liquid ejection apparatus. The second flow path is configured so that a rate of a pressure loss increases as a flow rate of the liquid flowing inside the second flow path increases.
