An adjustment drop number setting sectionsets a number of adjustment drops with which a change in print density in an image occurs remarkably when an ink drop amount of one ink drop is changed for each kind of a print medium (print sheet) input from an operation panelor sets uniformly regardless of the kind of print medium. When a density difference that requires adjustment is recognized visually between images by two neighboring ink heads on a density measurement chart printed by a chart printing execution section, the ink drop amount of one drop in the set number of adjustment drops is adjusted by adjusting a drive voltage of the ink head of a head unitaccording to an input from the operation panel
