Data processing device, image forming device, system, and a computer-readable recording medium for determining whether or not image is properly formed on recording medium

A data processing device comprising:

• an obtaining unit that obtains first and second image data sets;
• an image data generation unit that generates a third image data set by reading a second surface of a recording medium which has a first surface, on which an image has been formed in accordance with the first image data set by an image forming device, and the second surface on which an image has been formed in accordance with the second image data set by the image forming device;
• and
• a specifying unit that corrects the second image data set on basis of the first image data set, and specifies, as an error area, an area where a density difference between images expressed by the corrected second image data set and the third image data set is equal to or greater than a predetermined threshold,
• wherein the specifying unit obtains a property data set indicating a property of the recording medium, and determines the error area based on the property data set.
