An image forming apparatus that is capable of using a residual sheet effectively even in a double-sided printing mode. A control unit controls to perform a double-sided image formation process to recording sheets. A detection unit detects a jam of the recording sheet. A determination unit determines whether residual sheets, which are recording sheets on the conveyance path other than a jamming sheet that generates a jam, are available in the image forming process resumed after the jam is removed based on the number of copies of sheets on which the same image is formed, the recording sheets on which images have been formed on one sides, and the latest recording sheet that was normally ejected. The control unit stops the process and ejects the residual sheets that are determined unavailable from the conveyance path when a jam is detected during the process. |
