Patent ID: 8042900

Claim:
An inkjet recording apparatus, comprising: a treatment liquid deposition device which deposits on a recording medium a treatment liquid that insolubilizes or aggregates an ink; a recording head having a plurality of nozzles which eject the ink on the recording medium; a non-uniformity correction amount storage device storing non-uniformity correction amount data which are prepared with respect to each of the plurality of nozzles and determined according to ejection characteristics of each of the plurality of nozzles; a data acquisition device which acquires density data of an image; a non-uniformity correction amount revision device which revises the non-uniformity correction amount data for each of the plurality of nozzles, according to the density data related to another nozzle of the plurality of nozzles which ejects the ink that overlaps on the recording medium with the ink ejected by each of the plurality of nozzles, in such a manner that the non-uniformity correction amount data with respect to each of the plurality of nozzles are determined; a non-uniformity correction device which corrects the density data according to the non-uniformity correction amount data revised by the non-uniformity correction amount revision device; and an image forming device which controls the recording head according to the density data corrected by the non-uniformity correction device in such a manner that the image is formed on the recording medium.
