In an image recording apparatus, when an image is recorded on a recording medium, the recording medium passes through a head part only once. Before the image is recorded, a value of a color component of at least some of pixels included in the image is corrected in order to reduce color mixing unevenness. At that time, on the basis of respective values of two reference color components among a plurality of color components of a correction target pixel, a value of one target color component included among the two reference color components is corrected. Alternatively, on the basis of respective values of three reference color components among the plurality of color components, a value of one target color component or respective values of two target color components included among the three reference color components are corrected.
