An image processing apparatus includes a print processing portion, a first determination portion, a first determination target excluding portion, and a print color mode switching portion. The first determination portion determines, for each page of the document sheets, whether or not each of a plurality of divided areas is of a color type that is different from the print color mode. The first determination target excluding portion excludes divided areas that are determined as being of a color type that is different from the print color mode in a first set number or more of pages of the document sheets, from determination targets of the first determination portion from then. The print color mode switching portion is able to switch the print color mode during the print process when the number of divided areas that are the determination targets of the first determination portion becomes a predetermined number or smaller.
