Abstract
The ink jet recording method performs ink jet recording of an image on a recording medium using an ink jet head. The method allows an electrostatic force to act on ink prepared by dispersing charged particles containing colorants in a dispersion medium to form a thread of said ink, divides the thread into ink droplets of the ink to eject the ink droplets toward the recording medium and allows the ink droplets to be landed onto the recording medium moving relatively to the ink jet head to form an image dot on the recording medium. When a speed at which the recording medium and an ejection portion of the ink jet head for ejecting the ink droplets move relatively is referred to as 'v', a division frequency of the thread is referred to as 'f', and a diameter of the thread is referred to as “d”, the following expression is satisfied:()<()where “a” is a coefficient.
