ABSTRACT:
An electrostatic type ink-jet recording method wherein ink drops issuing from a nozzle are never placed adjacent one another in the direction of the deflection. According to one embodiment of the present invention, when a number of n contiguous ink dots are to be formed in each column in the direction of the deflection by deflecting the charged ink drops at a rate of a number of n ink drops per deflection interval, a number of n ink dots are divided into a number of m groups (where m<n) each consisting of a number of n/m ink dots spaced apart from each other by a distance nearly equal to m times the diameter of the ink dots, and in response to a print signal a first group of ink dots are formed in one deflection interval, next a second group are formed in the one deflection interval, and so on until a m-th group are formed, whereby the merging and bouncing apart of charged ink drops may be avoided.
