Abstract:
An image recording apparatus includes: a recording head having a plurality of recording elements; a conveyance device which conveys at least one of the recording head and a recording medium; a recording defect information acquisition device which acquires recording defect information; a recording defect correction device which corrects an image defect caused by the recording element having a recording defect; an image reading apparatus which reads in an image of a test chart for density measurement recorded by the recording head; a recording density information acquisition device which acquires recording density information indicating recording density of the plurality of recording elements; a density correction information calculation device which calculates density correction information; a density correction device which corrects density of image data; an uncorrected recording defect information acquisition device which acquires uncorrected recording defect information; and a recording density information amendment device which amends the density correction information.
