Zusammenfassung:	An image position inspecting apparatus includes a reading unit, a generating unit and a specifying unit. The reading unit includes light receiving elements arranged with a reading resolution Rs and reads an inspection image. The generating unit generates a profile based on the read inspection image. The specifying unit acquires a position of the center of gravity of the pixels of the inspection image with respect to the light receiving elements from the profile and specifies a position of each of the pixels of the inspection image based on a phase difference which is a deviation of the acquired position of the center of gravity of the pixels with respect to a light receiving center of the light receiving elements. A resolution of the inspection image is Rp. The reading resolution Rs and the resolution Rp satisfy the following equation. And, m is a positive integer. Rp·((m+1)/2)
