A raster image processor (RIP) generates intermediate data by interpreting PDL data, and stores it in a memory. In a case where the memory area overflows in the middle of intermediate data generation and storage processing on the print data for one page, rendering is executed based on the intermediate data. In accordance with JPEG XR, tile division is performed. An encoding parameter indicative of lossless-encoding or lossy-encoding is determined in accordance with each tile, and encoding is executed. The encoded image data is stored in a background image memory area as a background image of intermediate data that will subsequently be generated. When subsequent intermediate data generation is completed, rendering is executed, the rendered image is synthesized with the image saved as a background image, then the data is outputted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus which forms an image based on print data described in a page description language","description":"The present invention provides a technique for reducing image quality deterioration and suppressing print performance reduction.
