Abstract
An image forming apparatus is provided to smoothly form images corresponding to received image data even if the memory becomes full when collated printing is executed. If the memory never becomes full during collated printing, images for all of the pages are expanded to intermediate data, stored in a page memory, and complete collated printing is enabled. In the meantime, if the memory becomes full while the print data of part of a page is expanded to intermediate data and stored, the controller, controls so that the page memory can be written after collated printing is executed up to a page immediately before the partial page and the residual pages are printed in the form of collated printing. Therefore, even if the memory becomes full, printing can be executed in a form as close to collated printing as possible.
