Abstract: An image reading apparatus includes a first scanner configured to read a first image from a front side of a document, a second scanner configured to read a second image from a back side of the document, and first and second offset storage parts configured to store a first offset amount for correcting an inclination of the first image and a second offset amount for correcting an inclination of the second image, respectively. The image reading apparatus is configured to generate, when the first scanner is replaced, a new first offset amount based on the second offset amount, a first inclination amount of the first scanner, and a second inclination amount of the second scanner. The image reading apparatus is configured to correct the first image based on the new first offset amount.
