A method is provided for generating image data of a document by reading an image depicted on the document having a plurality of surfaces to be read. The method includes: reading, by an image reader, a surface image that is an image depicted on each of the surfaces; detecting, by an error detector, a faulty surface that is a surface of the plurality of surfaces of the document and corresponds to a scanned image on which an error occurs, the scanned image being obtained by reading the surface image; reading, by the image reader, the surface image repeatedly until the error is not detected; and generating, by an image data generating portion, the image data by merging data on the plurality of the scanned images on which the error is not detected and which correspond to the surfaces.
