A recording head of an ink-jet -recording apparatus has a plurality of nozzles, a plurality of pressure chambers connected to the plurality of nozzles respectively, and an ink saving chamber connected to the plurality of the pressure chambers for supplying ink into the pressure chambers and for temporarily saving the ink. An ink way is connected to the ink saving chamber for supplying the ink into the ink saving chamber. A driver causes respective pressures in the pressure chambers to change in such a manner that the ink is jetted from the nozzles so as to carry out flushing operations of the nozzles. A flushing controller causes the driver to carry out the flushing operations so that a flushing operation for a pressure chamber arranged relatively further from the ink way is delayed in starting for a predetermined time with respect to a flushing operation for another pressure chamber arranged relatively closer to the ink way. Thus, new ink is easily and sufficiently supplied into the pressure chamber arranged relatively further from the ink way during the flushing operation. This reduces the difference in viscosity of the ink in different portions of the ink saving chamber. Therefore, in the flushing operations, a sufficient volume of ink may be respectively jetted from the nozzles communicating with the pressure chambers, even if the pressure chambers are arranged far from the ink way.
