An image checking device checks a printed image printed out on a printing medium. The image checking device includes a data acquiring unit that acquires checking-image data, original reference image data input to an image forming device, and, from an attribute-information storage unit of the image forming device, attribute information about a printing medium; a correction-parameter storage unit that stores therein a correction parameter corresponding to the attribute information; an image generating unit that reads, from the correction-parameter storage unit, a correction parameter corresponding to the attribute information, corrects the original reference image data by using the correction parameter, and generates corrected reference image data; and an image checking unit that compares the checking-image data with the corrected reference image data by using a pre-set value to determine the degree of matching between the checking-image data and the corrected reference image data, thereby performing image checking on the printed image.
