摘要:
A spliced ink-jet head including head chips, each of which is capable of discharging inks of two or more colors, and which are spliced in a staggered manner which restrains the occurrence of splice streaks, white streaks caused by deflection at ends or uneven colors attributable to different landing orders of ink droplets in spliced portions of different colors when one-pass recording is carried out. The head chips is arranged such that, in a relationship between two adjoining head chips, at least one discharge port of one head chip and one discharge port of the other head chip for the same color tone ink in end portions overlap on a line in a recording material feeding direction, while discharge ports for different color tone inks do not overlap.
