Abstract
An inkjet recording apparatus including (A) a recording head including: plural nozzles discharging an ink drop to form an image on a receiving material; and plural pressure generators applying a pressure to the corresponding nozzles; (B) an ink container containing the ink, wherein the ink includes a pigment and a volatile solvent, and wherein the ink has a pigment content decreasing property such that the pigment content decreases at a meniscus portion of the ink in the nozzles when the ink is allowed to settle; and (C) a driver selectively actuating the pressure generators to discharge the ink from the corresponding nozzles, wherein the driver selectively actuates at least one of the pressure generators at a predetermined timing such that the ink at the meniscus portion is vibrated to an extent such that the ink is not discharged from the corresponding nozzle.
