Abstract: An image inspection apparatus for inspecting an image output on a recording medium. The image inspection apparatus includes processing circuitry that obtains data of an output-target image used by an image forming apparatus to conduct an image forming operation, generates read data from the data of the output-target image, and generates an inspection reference image from the data of the output-target image. The apparatus also performs position alignment between the read image and the inspection reference image, conducts an inspection which determines a defect in the read image based on the difference of the aligned read image and the inspection reference image, and determines whether a position alignment defect exists in the read image based on the defect detected during inspection.
