1. An image forming apparatus, comprising:
a print image generation unit configured to perform a first rasterization process for printing and thereby generate print image data, on the basis of a print request;
a print unit configured to perform printing based on the print image data onto a print paper sheet and thereby produce a print product;
an image scanning unit configured to perform image scanning of the print product and thereby generate scan image data; and
an inspection processing unit configured to perform inspection of the print product;
wherein the print image generation unit performs a second rasterization process for inspection on the basis of the print request and generates reference image data of plural reference images that have plural slant angles in a predetermined range, respectively; and
the inspection processing unit (a) determines a skew angle of the scan image data, (b) selects a reference image corresponding to the skew angle among the plural reference images, and (c) compares the reference image data of the selected reference image and the scan image data and thereby performs inspection of the print product.
