Title: Image forming apparatus, method for controlling image forming apparatus, and storage medium

Abstract: An image forming apparatus to generate image data of print data containing a drawing object for reuse within a job includes a cache unit, an object parallel processing unit, a page parallel processing unit, and a processing control unit. The cache unit generates data based on the drawing object and caches generated data. The object parallel processing unit divides each page of the print data per drawing object unit and subjects a divided page to raster image processor (RIP) processing in parallel. The page parallel processing unit subjects the print data to the RIP processing per page unit. The processing control unit controls such that, in the print data, the object parallel processing unit executes processing sequentially from an initial page until the data having a value equal to or more than a threshold value is cached and the page parallel processing unit executes processing after the data is cached.
