PURPOSE: To reduce a dispersion of image quality attributable to a nozzle by providing varied distances between a nozzle and recording paper which corresponds to each nozzle of plural nozzles.

CONSTITUTION: A multi-nozzle plate 10 has the injection surfaces of nozzles 1 and (n) at the end protruding beyond the nozzle surfaces of other nozzles 2W(n-1) toward recording paper 40, and the difference Δx is provided on the nozzle injection surface. This difference Δx is set so that ink droplets injected from the nozzles at the end and those from other nozzles may have the same deflection value. Thus it is made possible to prevent deterioration of image quality caused by a dispersion of deflection value under a simple and low-cost configuration.
