Abstract: An image scanner includes a transparent plate (13), a scanning device (21), a driving device, a positioning member (17), a black reference portion (17b) and a white reference portion (17a). The transparent plate has an original placing surface. The scanning device irradiates an original (P) with light by means of a light source and scans reflected light from the original. The driving device reciprocates the scanning device along the transparent plate. The positioning member positions the original placed on the original placing surface of the transparent plate. The black reference portion, which is disposed on the original placing surface side of the positioning member and at substantially a central portion of the positioning member in moving directions of the scanning device, absorbs ambient light entering to the original placing surface side of the positioning member through the transparent plate. The white reference portion is provided to the original placing surface side of the positioning member.
