An inkjet recording apparatus has a recording head which has a nozzle row composed of a plurality of nozzles for ejecting ink, a storage device which stores local variation processing parameters determined according to nozzle locality showing displacement from an ideal state of dot depositions due to defectiveness of the nozzles, a digital halftoning processing device which converts inputted image data to dot data, a local variation processing device which varies the dot data obtained by the digital halftoning processing device so as to compensate the nozzle locality by using the local variation processing parameters stored in the storage device, and a control device which controls ink ejection of the plurality of nozzles of the recording head according to the dot data generated through processing by the local variation processing device.
