1. An image forming apparatus configured to perform, based on a print job to be input, double-sided printing in which front and back of a recording material is reversed on a conveying path after a first side of the recording material is printed and thereafter a second side of the recording material is printed, or single-sided printing in which a first side of a recording material is printed and the recording material is discharged, the image forming apparatus comprising:

  • a feeder configured to feed the recording material;

    an image forming unit configured to form an image on the recording material according to image data;

    a discharge tray to which the recording material with the image formed is discharged;

    a detector configured to detect a characteristic of the recording material fed by the feeder; and

    a controller configured to determine whether the recording material supports the double-sided printing or not based on a detection result of the detector for the recording material fed by the feeder;

    wherein the controller is further configured to control the image forming unit to form an image of an even-numbered page of the print job on the first side of the recording material in an order of page number, to discharge a recording material with an image formed on a first side to a discharge tray, to prompt a user to place the discharged recording material on a feeder for second side printing, and to control the image forming unit to form an image of an odd-numbered page on the second side of the recording material with the image formed on the first side which is fed from the feeder for the second side printing if it is determined that double-sided printing is specified by the print job and the recording material does not support the double-sided printing based on a detection result of the detector.
