    Abstract: An image reading apparatus of the present invention includes a first light source, a first light guide, a second light source, a second light guide, light receiving elements and a lens unit. The first light source emits first light. The first light guide directs the first light from the first light source toward an image-carrying object as first linear light extending in a primary scanning direction. The second light source emits second light of a wavelength different from that of the first light. The second light guide directs the second light from the second light source toward the image-carrying object as second linear light extending in the primary scanning direction. The light receiving elements are arranged in the primary scanning direction. The first and second linear lights are reflected by the image-carrying object, and the reflected lights are guided by the lens unit toward the light receiving elements.
