Abstract

A liquid supplying apparatus for supplying a liquid to an ejecting device. The liquid supplying apparatus includes a liquid storage device, a supply device, a first gas-permeable membrane, and a gas blocking liquid. The liquid storage device, including a reservoir having an atmosphere communication hole in an upper portion of the reservoir, stores the liquid. The supply device applies pressure to the liquid and supplies the liquid to the liquid storage device. The first gas-permeable membrane, which is permeable to gas but impermeable to liquid, is disposed in the atmosphere communication hole. The gas blocking liquid, filled in the atmosphere communication hole on the atmosphere side of the first gas-permeable membrane, prevents entry of gas from the atmosphere side.
