The image reading apparatus includes a first conveyance roller pair, a back side image reading unit, a second conveyance roller pair, a front side image reading unit, a third conveyance roller pair, and a control unit. The control unit compares the image data read by the back side image reading unit and the image data read by the front side image reading unit to calculate a relative magnification variation there between, corrects the reading time of the front side image reading unit for each line based on the calculated relative magnification variation, and performs, in accordance with correction of the reading time, image correction of the image data of the front side image reading unit which has been corrected with respect to the reading time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image reading apparatus and image forming system","description":"An image reading apparatus can inhibit image disturbance and density unevenness.
