ABSTRACT:
The image forming apparatus includes: a liquid ejection head including a plurality of nozzles, the liquid ejection head ejecting a first liquid containing a coloring material through the nozzles onto a recording medium while the liquid ejection head and the recording medium are relatively moved in a first direction; an abnormal nozzle identifying device which identifies, out of the nozzles, an abnormal nozzle for which an error in a landing position of the first liquid on the recording medium with respect to a second direction orthogonal to the first direction is not less than a predetermined amount; and a correcting device which corrects dot data in such a manner that a second dot on the recording medium formed from the first liquid subsequently ejected from the abnormal nozzle makes contact with at least part of a first dot on the recording medium formed from the first liquid previously ejected from the abnormal nozzle.
