Abstract
An image forming apparatus includes a discharge disabling unit configured to disable a discharge operation of a defective nozzle, which is in a defective discharge state, among a plurality of nozzles configured to discharge liquid droplets to a recording medium, when a value obtained by quantifying a degree of defective state of the defective nozzle is greater than a discharge disable threshold value; a complement unit configured to complement an image defect using two nozzles on either side of the defective nozzle of which discharge operation is disabled; and a threshold value change unit configured to change the discharge disable threshold value depending on a discharge order between the nozzles which complement the image defect and nozzles adjacent to the nozzles which complement the image defect.
