PURPOSE:To form a document having emphasis of a specific color and to perform halftone recording by applying processing for changing the size of the ink droplet emitted from an orifice corresponding to the color of ink to the orifice and an energy acting part or the vicinities of them. CONSTITUTION:A plurality of passages 8 into which two or more kinds of inks different in color are introduced at every inks are provided. Energy acting parts 6 applying emitting energies to the inks in the passages 8 and the orifices 11 communicating with the passages 8 and emitting a part of the inks to which emitting energies are applied as ink droplets are provided. Altering processing changing the sizes of the ink droplets emitted from the orifices corresponding to the colors of the inks introduced into the passages 8 is applied to the orifices 11 and the energy acting parts 6 or to the vicinities of them. |
