ABSTRACT:
An image forming apparatus which is capable of feeding paper from a paper feeding unit when paper types set in selected paper feeding units are all the same type even if the selected paper feeding units do not include a paper feeding unit in which a predetermined paper type is set. At least one of paper feeding portions stacking a paper with the designated paper size is selected based on an attribute set to each of a plurality of paper feeding portions. in a case where a selected plurality of paper feeding portions do not include a paper feeding portion set with the predetermined attribute when the attributes set to the selected plurality of paper feeding portions are the same, a paper is fed to the image forming unit from any one of the selected plurality of paper feeding portions.
