摘要:
An ink jet recording apparatus for ejecting droplets of ink from a plurality of nozzles is provided. The recording apparatus comprises a nozzle plate having the plurality of nozzles and a pressure generator associated with each of the plurality of nozzles. The nozzles and said pressure generators are disposed in at least three groups and each of the groups are associated with a single color ink. The ink associated with one group of nozzles and pressure generators is lighter, and the ink associated with one group of nozzles and pressure generators is darker than the ink associated with the other groups of nozzles and pressure generators. The group of nozzles and pressure generators associated with the ink of the lightest color is situated furthest from the group of nozzles and pressure generators associated with the ink of the darkest color. The recording apparatus also comprises first reservoir means for storing ink formed between the nozzle plate and the pressure generating means having a first cross-sectional area, support means for supporting the pressure generating means and having a slit having a second cross-sectional area for supplying ink to the first reservoir means, and second reservoir means in fluid communication with the slit for storing ink having a third cross-sectional area wherein the first cross-sectional area is smaller than the second cross-sectional area and the second cross-sectional area is smaller than the third cross-sectional area for promoting capillary action in ejecting droplets of ink through the plurality of nozzles.
