Abstract
In order to provide an image forming apparatus which controls unnecessary image formation without reducing productivity, at the time of automatic sheet selection, the number of image sheets M which can be present from the writing position of images using the image writing section to the transfer position of the transfer section and the number of sheet N which can be present from the sensors which detect the no-paper state in each of the plurality of sheet feeding sections to the transfer position of the transfer section are obtained, and then the sheet feeding section which satisfies M<N is preferentially selected.
