A liquid supplying device includes a liquid supplying flow path for supplying liquid from an upstream side toward a downstream side on which the liquid is consumed. A pump is driven for a pumping operation in accordance with displacement of a displacement member constituting a part of an inner wall of a pump chamber as a part of the liquid supplying flow path for changing the volume of the pump chamber. A detecting unit detects the remaining amount of the liquid of the liquid supplying source. The liquid supplying source is configured such that the volume of a liquid housing part as a closed space housing the liquid changes in accordance with the remaining amount of the liquid, and the detecting unit detects a liquid-end state in which the none of the liquid inside the liquid housing part remains based on the amount of displacement of the displacement member.
