To provide an image processing device having a plurality of image processing functions, configured to inspect an image by comparing an image formed by reading a result of image formation output with a master image.

An inspection apparatus 2 for inspecting a read image formed by reading an image formed and output on a sheet by an MFP 1 having a plurality of image processing functions includes: a master image processing part 202 which acquires bitmap data converted in the MFP 1 to generate a master image to be used for inspecting the read image; an inspection control part 205 that determines a defect of the read image on the basis of a difference between the master image and the read image; and a comparison inspection part 206. The master image processing part 202 generates a master image by performing image processing according to an information format of the acquired bitmap data.
