Provided is an image processing apparatus, an image processing method, and a recording medium capable of reproducing a plurality of copies of a document bundle while reducing the storage capacity of a storage device. In the image processing apparatus, a number of copies of a document bundle to be a reading target by an image reading unit that reads image data from each of the documents included in one or a plurality of copies of a document bundle is specified. Then, in a case where the specified number of copies of the document bundle is plural, document bundle image data corresponding to one copy of the document bundle of the image data read by the image reading unit, and specification information including at least the number of copies of the document bundle specified by the specification processing unit are correlated and stored.
