ABSTRACT:
In an ink-jet recording apparatus, an active portion for jetting a pigment ink has an area greater than an area of an active portion for jetting a dye ink. Accordingly, the active portion for jetting the pigment ink is capable of generating energy greater than that generated by the active portion for jetting the dye ink. In addition, since a diameter of nozzles which jet the pigment ink is greater than that of nozzles which jet the dye ink, it is possible to jet, at a substantially same speed, the pigment ink and the dye ink to which the different energies are imparted. Further, when performing the recording with the pigment ink, a liquid-droplet having a large volume can be obtained, and when performing the recording with the dye ink, a liquid-droplet having a small volume can be obtained.
