ABSTRACT:
An ink-jet recording apparatus includes an ink tank in a layered form and having a plurality of ink storage chambers storing color inks; a driving circuit; a heat transfer plate; and a recording head having a plurality of nozzle rows arranged in one direction. The heat transfer plate is in contact with the driving circuit and faces, at a spacing distance, an ink storage chamber, among the ink storage chambers, storing a yellow ink included in the color inks, and formed on the lowest layer of the ink tank. The yellow ink is supplied to a center nozzle row among the nozzle rows. This construction reduces an influence on printing quality due to variation in extent by which the color inks are influenced by the heat from the driving circuit, thereby providing an ink-jet recording apparatus which can realize high-quality printing and made to be compact.
