<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus wherein processing loads when converting page data into raster image data are reduced. <P>SOLUTION: The image forming apparatus includes: a PDF storage part 32 for holding the page data composed of the relating information of PR information not shared by other print pages and SR information shared by the other print pages; rendering parts 35 and 36 for converting the PR information and the SR information into the raster image data; a raster image storage part 37 for holding the raster image data; and a raster image combining part 38 for combining the raster image data converted from the SR information and the PR information and generating image data for each print page. When converting the SR information into the raster image data, the SR rendering part 36 discriminates whether or not the raster image data corresponding to the SR information are already held and performs the generation processing of the raster image data by rendering. <P>COPYRIGHT: (C)2009,JPO&INPIT |
