A liquid supply system includes a liquid supply source with a liquid container portion accommodating liquid inside and a liquid delivery portion that delivers the liquid outside. A liquid supply flow passage supplies the liquid from an upstream side of the liquid supply source, toward a downstream side at which the liquid is consumed. A pump is driven using a portion of the liquid supply flow passage as a pump chamber. A first one-way valve in the liquid supply flow passage at a position downstream of the pump chamber allows the liquid to pass only from the upstream side to the downstream side. A second one-way valve in the liquid supply source allows the liquid to pass only from an upstream side of the liquid container portion, to a downstream side of the liquid delivery portion.
