Abstract
When a drive frequency for an electrode used to cause an electrostatic force to act on an ink composition is assigned A, and a division frequency for a thread is assigned B, a relationship of A≧5 kHz and B/A≧5 is met, and a division frequency for the thread is reduced for a time period required to apply a pulse voltage to the electrode in order to eject the ink composition. As a result, it is possible to provide an electrostatic ink jet recording method with which excellent gradation controllability and controllability for dot diameters in a shadow area can be realized.
