Image processing capable of monochrome output by enhancing the distinctiveness of color document

An image forming apparatus comprising:

• a monochrome visual determination unit configured to determine whether or not visual distinctiveness of a color portion is low when document data having the color portion is output in monochrome;
• a monochrome presentation unit configured to present to a user when there is the color portion that the distinctiveness is determined to be low by the monochrome visual determination unit;
• and
• an image forming unit configured to output the document data when presented by the monochrome presentation unit and instructed by the user;
• wherein
• the monochrome visual determination unit searches a character sequence of the document data for a keyword including a color name and determines that the visual distinctiveness is low when it is determined that both a) the character sequence has the keyword including the color name and b) the color portion includes a color corresponding to the color name.
