IMAGE INSPECTION APPARATUS, IMAGE FORMING APPARATUS, IMAGE INSPECTION METHOD, AND IMAGE INSPECTION PROGRAM

An image inspection apparatus for inspecting a recording medium having first and second sides is devised. The image inspection apparatus includes a penetrated-image information obtaining unit to obtain information of penetrated-image; an inspection information storage to store information of upper permissible limit of image penetration; a pre-print image penetration inspection unit to obtain an image penetration level from the first side to the second side, to compare the obtained image penetration level and the upper permissible limit, and to inspect an image penetration from the first side to the second side; a pre-print image penetration prediction unit to predict, before an image is formed on the second side, an image penetration level from the second side to the first side; and a post-print image inspection unit to inspect images on the first and second sides after forming the image on the second side.
