An image reading apparatus includes a plurality of reading sections (CCD elements) and reads a photographic photosensitive material by pre-set plural reading sections of the plurality of reading sections. In the image reading apparatus, on the basis of a value indicating an amount of deviation between an actual reading position and a predetermined proper reading position, the plural reading sections which read the photographic photosensitive material are suitably shifted from pre-set plural reading sections. Accordingly, even if a reading device deviates from its proper position, an entire range to be read of the photographic photosensitive material can be read. Specifically, first, a position H1, at which a reference position of the photographic photosensitive material is actually imaged on the reading device (a line CCD sensor), is fetched. Next, a proper imaging position H0, at which the reference position of the photographic photosensitive material should be imaged on the reading device, is fetched. An amount of deviation DeltaH itself (i.e., a difference between the proper imaging position H0 and the actual imaging position H1) is calculated by the formula Delta H=H0-H1. Then, a range of CCD elements selected in advance to read only the photographic photosensitive material is moved, in a direction of eliminating the calculated deviation, by a number of CCD elements corresponding to the amount of deviation.
