ABSTRACT:
An ink jet recording device comprises a recording head for ejecting pigmented ink in an ink chamber, an ink reservoir for circulating the pigmented ink between the ink chamber and the ink reservoir, and a replenishment tank for replenishing concentrated pigmented ink to the ink reservoir. The replenishment of the concentrated pigmented ink is effected by a piezoelectric element for reducing the volume of the replenishment tank upon receiving a driving signal. The concentration of colored particles in the concentrated pigmented ink is equal to the concentration of the colored particles in the ink droplet ejected from the ink chamber.
