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 print head and a solvent chamber in a solvent supply path from a solvent container to the print head. 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. In order to prevent a backflow of the solvent from the solvent chamber to the solvent container, a check valve (may be an electromagnetic valve) is provided. While the ink is not being supplied, a space in the solvent chamber is configured to be ensured by a repellant force of the spring.
