An ink supplying device is provided and supplies a functional ink to a droplet ejecting portion, including: a tube body through which the functional ink passes; a degasser that removes a dissolved gas from the functional ink; a first supply path in which the degasser is fitted to the tube body; a second supply path in which the degasser is not fitted to the tube body; and a controller that switches a supply path of the functional ink to the second supply path when a viscosity of the functional ink is higher than or equal to a predetermined value, and switches the supply path to the first supply path when the viscosity of the functional ink is lower than the predetermined value. The first supply path and the second supply path are coupled by an upstream side coupling portion and a downstream side coupling portion.
