An image inspection device inspects an inspection image obtained by reading a sheet. The image inspection device includes a hardware processor that: performs inspection by comparing the inspection image with a reference image that is obtained by reading the original image that is printed on the sheet; determines whether a possibility of abnormality exists in the reference image based on a difference between the reference image and the inspection image; displays a difference portion between the reference image and the inspection image when determining that the possibility of abnormality exists in the reference image; receives a selection of a normality or an abnormality for each of the reference image and the inspection image; and replaces the reference image with the inspection image when the abnormality is selected for the reference image and the normality is selected for the inspection image.
