Abstract
An image reading apparatus includes a transporting member that transports a document, a light source that irradiates the document at a reading position with light, a light receiving unit that receives light reflected at the reading position, a background member that is inclined with respect to the document at the reading position such that, upon reflecting the light emitted from the light source toward the light receiving unit when the document is not present at the reading position, a difference between an incident angle and a reflection angle thereon is less than a difference between an incident angle and a reflection angle on the document at the reading position, and an adjusting unit that adjusts a position or attitude of an acting member such that the light reflected from the background member is received with a greater intensity than light reflected from white paper at the reading position.
