Abstract:
1. An image forming apparatus comprising: an image forming section configured to print on a sheet; a sheet feeding section configured to feed sheets one by one to the image forming section for printing on a first side thereof; a re-feeding section configured to, when double-sided printing is to be performed, re-feed the fed sheets to the image forming section for printing on a second side thereof; and a control section configured to perform, when there is a page of double-sided printing, which is posterior to a page of single-sided printing, a passing control where a sheet for the page of double-sided printing is fed and printed with the page of double-sided printing on the first side thereof before a sheet for the page of single-sided printing is fed and printed on the first side thereof, wherein when an occurrence of a state is predicted, where the sheet for the page of single-sided printing, which is to be fed and printed after the sheet for the page of double-sided printing in the passing control, cannot be fed, the control section does not perform the passing control so that the page of single-sided printing, instead of the page of double-sided printing, printed on the sheet to be fed and printed with the page of double-sided printing, after the image forming section has completed printing on all already fed sheets re-fed from the re-feeding section.
