Abstract: A liquid supply device includes a supply tank and a pressurizer. The supply tank stores a liquid to be supplied to a liquid ejection head. The pressurizer provides a positive pressure to the supply tank through a gas to cause an internal space of the supply tank to have a positive pressure higher than an atmospheric pressure. The pressurizer includes a supply regulator, a pressurizing tube, and a branch tube. The supply regulator lowers a pressure of a gas from a pressure source. The pressurizing tube connects the supply regulator to the supply tank to allow the gas with the pressure lowered by the supply regulator to flow to the supply tank. The branch tube branches from a point on the pressurizing tube and includes a terminal end being open to atmosphere.
