ABSTRACT:
The inkjet recording method and apparatus eject ink droplets made of an ink composition on a recording medium to record. The method and apparatus use insulating ink prepared by dispersing colorant particles capable of being charged in a solvent as the ink composition, allow an electrostatic force to act on the ink composition to form a thread of the ink composition and provide a stimulus to the thread at a frequency in a range of 100 kHz to 800 kHz to separate the thread into the ink droplets. The apparatus includes an inkjet head for ejecting the ink droplets, an electrode substrate for applying a charging voltage to the recording medium and a stimulus providing unit for providing the stimulus.
