Abstract
An inkjet print head includes one nozzle sheet (23) and a plurality of head chips (25) including a plurality of heaters. The nozzle sheet (23) is formed of an electroformed metal layer made of nickel or a material comprising nickel, and has discharge nozzle rows for respective colors disposed so that the discharge nozzles are in staggered arrangements and so that each set of discharge nozzles partly overlaps another set of discharge nozzles in a sheet-feed direction. The head chips are positioned at and affixed to a growth surface side of the nozzle sheet (23) in staggered arrangements so that the positions of the discharge nozzles and the positions of the heaters correspond to each other. Accordingly, reduction in printing quality caused by displacement of any of the discharge nozzles is prevented from occurring, and landing positions of discharged ink on a recording sheet are stabilized.
