Abstract
A cover member is openable and closable with respect to a document table, and has a color reference surface facing the document table, and a partial region provided on a color reference surface and having a predetermined density different from a density of the color reference surface. When a document determination portion determines that a document is a book document, a density correction portion corrects a density in a specific density correction range at a central portion in document image data read from a document by a image reading portion, based on a second density difference which is a density difference between a density of the color reference surface read by a reading control portion when a book document is placed on a document placement surface, and a density of the color reference surface read by the image reading portion when the cover member is closed.
