An image recording apparatus for recording an image on a recording medium, comprising: a head part for ejecting droplets of ink toward a recording medium; a moving mechanism for moving said recording medium relative to said head part in a moving direction; an output control part for controlling ejection of ink from said head part in synchronization with relative movement of said recording medium; and a correction part for correcting values of a color component of at least some of pixels included in said image, wherein said head part includes a plurality of ink ejection parts for ejecting droplets of inks having color components different from one another and said plurality of ink ejection parts are arranged in said moving direction, each ink ejection part includes a plurality of ejection ports arranged across a recording range on said recording medium with respect to a width direction perpendicular to said moving direction, said recording medium passes through said head part only once when an image is recorded on said recording medium, said each ink ejection part includes a plurality of ejection units arranged in said width direction, and respective end portions of ejection port rows of adjacent ejection units in said width direction overlap each other in said moving direction, characterized in that pixels corresponding to both ends of a range in said width direction, said range in which said ejection port rows overlap each other, are included among targets of correction to be performed by said correction part, and said correction part corrects a value of one target color component which has larger effect on the intensity of color mixing unevenness among two reference color components determined out of a plurality of color components of a correction target pixel, said two reference color components being determined on the basis of easiness of occurrence of color mixing unevenness, or corrects a value of one target color component or respective values of two target color components which have largest or larger effect on the intensity of color mixing unevenness among three reference color components determined out of said plurality of color components, said three reference color components being determined on the basis of easiness of occurrence of color mixing unevenness. a head part for ejecting droplets of ink toward a recording medium; a moving mechanism for moving said recording medium relative to said head part in a moving direction; an output control part for controlling ejection of ink from said head part in synchronization with relative movement of said recording medium; and a correction part for correcting values of a color component of at least some of pixels included in said image, wherein said head part includes a plurality of ink ejection parts for ejecting droplets of inks having color components different from one another and said plurality of ink ejection parts are arranged in said moving direction, each ink ejection part includes a plurality of ejection ports arranged across a recording range on said recording medium with respect to a width direction perpendicular to said moving direction, said recording medium passes through said head part only once when an image is recorded on said recording medium, said each ink ejection part includes a plurality of ejection units arranged in said width direction, and respective end portions of ejection port rows of adjacent ejection units in said width direction overlap each other in said moving direction, characterized in that pixels corresponding to both ends of a range in said width direction, said range in which said ejection port rows overlap each other, are included among targets of correction to be performed by said correction part, and said correction part corrects a value of one target color component which has larger effect on the intensity of color mixing unevenness among two reference color components determined out of a plurality of color components of a correction target pixel, said two reference color components being determined on the basis of easiness of occurrence of color mixing unevenness, or corrects a value of one target color component or respective values of two target color components which have largest or larger effect on the intensity of color mixing unevenness among three reference color components determined out of said plurality of color components, said three reference color components being determined on the basis of easiness of occurrence of color mixing unevenness.
