An image processing apparatus which is able to make a copy whose character information is clearly readable for a predetermined document registered as a special document is provided. A fixed-format document including the character information written in a predetermined format is determined as the special document and the special document identification information for identifying the special document is stored. An original document determining unit compares document color distribution information (color distribution information relating to a sample area of a special document) retained as the special document identification information with original document color distribution information (color distribution information of an area corresponding to the sample area of the special document) and, when the both of them match, the original document is determined to be a special original document. When the original document corresponds to the special document, image data acquired by reading out the original document is converted into monochrome image data and is recorded on a recording sheet.
