Abstract

PURPOSE: To improve printing quality in a charging deflection type ink-jet printer by charging ink drops in a specified order.
CONSTITUTION: Ink drops jetted from an ink-jet head are charged and deflected by deflecting electrodes to print a recording paper. In this case, when the maximum number of columns to charge ink drops is M, each column is divided into the number K of lines which is obtained by dividing the maximum number M of charging columns by a natural number N (N≥3), and charging is performed in the order of lines. Moreover, on the first line, charging is performed so as to start from an arbitrary column (≤K) and skip over K; on the second line, from an intermediate column L and skip over K; on the third column, from an intermediate column P and skip over K and so on. Thereby, the influences of air resistance and coulomb force exerted by a preceding charged ink drop on a succeeding charged ink drop can be minimized, so that ink drops are allowed to fly substantially independently of each other.
