An image processing system includes intermediate-data generating apparatuses and one or more drawing-data generating apparatuses. The intermediate-data generating apparatuses interpret data of pages forming PDL document data, the pages being assigned to the corresponding intermediate-data generating apparatuses, to generate elements of intermediate data of the pages. The drawing-data generating apparatuses each obtain assigned elements of the intermediate data and each draw the obtained elements to generate drawing data including information concerning pixels forming each obtained element. The drawing-data generating apparatuses each include a memory that stores intermediate data or drawing data of a common element used in the obtained elements. If the intermediate data or the drawing data of the common element is stored in the memory, the drawing-data generating apparatuses generate drawing data of the obtained elements using the stored intermediate data or drawing data. The number of drawing-data generating apparatuses is smaller than that of intermediate-data generating apparatuses.
