Abstract

PURPOSE:To enable color recording without a decrease in resolution at an medium tone density by making a nozzle orifice diameter of an ink jet head which jets a black ink smaller than those of the heads that jet out color inks. CONSTITUTION:An ink jet head 10 is provided with a nozzle 12 which has an orifice 11 which jets ink droplets. Within a variation of recording dot diameters of the time when an orifice planar dimension is changed, the dot planar dimensions are approximately proportional to the orifice planar dimensions. If an orifice 11 diameter of the ink jet head 10 which jets a black ink and which is smaller than those of the orifice 11 of the jet heads 10 which jet out three primary color inks is used, jetting of smaller dot diameters becomes feasible and through the variation of dot planar dimensions an excellent resolution recording may be carried out, including recording of a low density.
