Abstract
A configuration of an image display apparatus which can reduce a pump exclusive for solvent is provided. The image display apparatus of the present invention is provided with an ink chamber in an ink supply path from an ink container to a printhead and a solvent chamber in a solvent supply path from a solvent container to the printhead. The ink chamber and the solvent chamber are formed by dividing a liquid chamber by an elastic member (diaphragm), and volumes (capacities) of the ink chamber and the solvent chamber are changed by a pressure of the ink.
