Abstract
An image forming apparatus capable of improving productivity in a print job mixedly involving single-sided printing and double-sided printing. Sheets are fed one by one to an image forming section. When double-sided printing is to be performed, a sheet having an image formed on the first side thereof by the image forming section is re-fed thereto so as to have an image formed on the second side thereof. When a sheet for double-sided printing exists, which is posterior in page order to a sheet for single-sided printing, an image forming order is changed such that the first side of the sheet for double-sided printing is subjected to image formation prior to the sheet for single-sided printing. When it is predicted that a state will occur in which the sheet for single-sided printing cannot be fed, the image forming order is not changed.
