Abstract
A liquid ejecting apparatus includes a flow channel through which liquid is supplied to a liquid ejecting head, a gas permeable film that constitutes a wall surface of the flow channel, an air chamber that is separated from the flow channel through intermediation of the gas permeable film, and a pressure regulating section for changing an air pressure inside the air chamber with respect to a reference pressure. The gas permeable film is configured to change a volume of the flow channel through a change in the air pressure inside the air chamber with the pressure regulating section, and allow permeation of an air bubble when the pressure regulating section decreases the air pressure inside the air chamber.
