An image reading apparatus includes an image reading unit which reads a manuscript image by optically scanning a manuscript placed on a reading region, a region division unit which divides the reading region into a plurality of partial regions in accordance with a division direction directed along a sub scanning direction to which the image reading unit moves for scanning the manuscript and a division direction directed along a main scanning direction perpendicular to the sub scanning direction, a condition setting unit which sets a condition on which the image reading unit reads the manuscript image for each of the partial regions, and a controller which directs the image reading unit to read the manuscript image on the conditions depending on the partial regions being scanned by the image reading unit.
