Abstract:
An inkjet recording head which scans in a direction intersecting a conveyance direction of a recording medium and records an image on the recording medium with ink drops ejected from nozzles, the inkjet recording head comprising:a nozzle plate in which the nozzles which eject the ink drops are formed; pressure chambers communicating with the nozzles; actuators abutting at the pressure chambers, which at least one of increase and reduce pressures of ink in the pressure chambers; and a nozzle row parallel to the conveyance direction of the recording medium, wherein the inkjet recording head includes a plurality of nozzle groups structured by dividing up the nozzle row, and the nozzles of the nozzle row include opposing nozzles which are disposed at a boundary between neighboring nozzle groups which neighbor in the row direction of the nozzle row, the actuators include opposing actuators, which respectively correspond to the opposing nozzles, and actuators within the nozzle groups, which respectively correspond to nozzles neighboring the opposing nozzles in the row direction, and a separation between the opposing actuators disposed at the boundary is equal to or greater than separations between the opposing actuators and the actuators neighboring the opposing actuators in the row direction within the nozzle groups.
