ABSTRACT:
A multi-nozzle type ink jet recording apparatus arranged so as to eject ink from each of a plurality of ink nozzles toward a writing surface by means of an electric field established due to an ink ejecting signal applied to each of the ink nozzles. The ink jet recording apparatus includes a circuit for generating a density information signal indicative of a recording density at every ink nozzle and a control unit being responsive to the density information signal and having a plurality of memories. Each of the plurality of memories stores a density-to-signal characteristic being predetermined to correspond to one or more of the ink nozzle and the density-signal characteristic represents the relation between the recording density and the ink ejecting signal indicative of an ink ejecting amount ejected from each of the ink nozzles. The control unit selects one from the density-to-signal characteristics at every ink nozzle and generating the ink ejecting signal indicative of the ink ejecting amount determined on the basis of the density information signal from the density information signal generating circuit in accordance with the selected density-to-signal characteristic, the generated ink ejecting signal being applied to the corresponding ink nozzle.
