Abstract

An image processing apparatus includes an image compressing unit, and a print-data generating unit. The image compressing unit divides the image of one page's worth of the document into each band region by a predetermined width in the sub-scanning direction and sets a rectangular region by a further division of each band region by a predetermined width in the main-scanning direction to generate rectangular compressed data. When the print-data generating unit generates the print data where a plurality of pages of document image are aggregated in one sheet, and an region in which the image does not exist occurs in a last page after the aggregation, the storing control unit complements the region in which the image does not exist in the rectangular compressed data storage unit using the white image data stored in the white image data storage unit.
