An ink jet printing method by means of an electrostatic type ink jet printing apparatus, in which charging stages forming one scanning line on a recording sheet paper are divided into groups, ink droplets for printing each group being so charged that they impinge on the scanning line at intervals of a predetermined number of stages, the groups having starting stages different from each other, which results in that the influence of the aerodynamic resistance due to the preceding ink droplets on the ink droplet concerned and that of the Coulomb's force due to the preceding and neighboring ink droplets on the ink droplet concerned are suppressed to the minimum and, consequently, the quality of printing is considerably improved.
