An image forming apparatus according to this invention which allows double-sided printing can reduce the toner consumption amount by decreasing the size of a developer image on the second page as compared with the size of a developer image printed on the first page in margin-less printing. To accomplish this, the image forming apparatus includes a setting unit adapted to set, when images are to be formed on both surfaces of a printing material without margin, a size of a developer image on a second page of the printing material smaller than a size of a developer image on a first page of the printing material.

Image forming apparatus and control method for printing without a margin

An image processing method and system is provided wherein a plurality of processors perform a conversion process from a page description language format of data into raster image data, and a printing engine which continuously receives color image data having at least three color components in page unit and prints the at least three color components of color image data on a recording medium in parallel at a constant speed. A page description language format of data is received that includes at least two of the at least three color components as at least an object constituting the page description format data, the page description language format of data is analyzed and, based on the analysis, each color component data of the object in the received data is assigned to each processor such that the plurality of processors perform the conversion processes of the at least two of the at least three color components in parallel thereby producing raster image data of each color component from the plurality of processors to the printing engine in parallel.
