Abstract: A liquid ejecting apparatus includes a liquid flow path connecting a liquid containing unit that contains a liquid to a liquid ejecting unit that ejects the liquid. The liquid flow path includes a supply flow path which connects the liquid containing unit to the liquid ejecting unit and a return flow path which connects the liquid ejecting unit to the liquid containing unit. When the liquid is not ejected by the liquid ejecting unit, the liquid contained in the liquid containing unit is circulated between the liquid containing unit and the liquid flow path by allowing the liquid to flow in order of the supply flow path, the liquid ejecting unit, and the return flow path. When the liquid is ejected, the liquid contained in the liquid containing unit is supplied to the common liquid chamber via both of the supply flow path and the return flow path.
