Refilling of a used liquid container of a liquid ejector such as an ink-jet apparatus is carried out by sequentially performing the steps of drawing out liquid remaining in the liquid container by way of a liquid outlet port of the liquid container, reducing the inner pressure of the evacuated liquid container by way of the liquid outlet port, and filling liquid from a liquid supply tank into the liquid container by way of the liquid outlet port. The liquid drawn out from the liquid container is fed back into the liquid supply tank.
