In an ink jet recording device in which a paper supporting part is constituted by a first support and a second support having a comb teeth structure, a region where paper is supported by only the first support is defined as a first region, a region where the paper is supported by only the second support is defined as a second region, and a region where the paper is supported by the first support and the second support is defined as a third region. Charts including a plurality of grayscales for the respective regions are drawn. The respective drawn charts are read by an image reader. Correction values of density unevenness are obtained for the respective regions on the basis of the reading results. Density data of an image are corrected for the respective regions on the basis of the correction values of the density unevenness for the respective regions.
