Claim:
An image forming apparatus, comprising: a main conveyance path configured to convey a recording medium; a double-side reversing conveyance path configured to switch back the recording medium, one side of which has an image formed thereon, so as to reverse sides of the recording medium for double-sided image formation; a sheet resending conveyance path configured to resend the recording medium reversed in the double-side reversing conveyance path to the main conveyance path; a double-side reversing open-space unit configured to provide a space for switching back the recording medium on the double-side reversing conveyance path, and configured to serve as a temporary tray; a double-side reversing roller configured to convey the recording medium to the double-side open-space unit by rotating in a forward direction and resend the recording medium into the sheet resending conveyance path by rotating in a backward direction, the backward direction being opposite to the forward direction; a detection unit disposed at a position downstream of the double-side reversing roller in the forward direction or in a vicinity of the double-side reversing open-space unit and configured to detect presence and absence of a recording medium remaining inside the image forming apparatus stored in the temporary tray for storing therein the recording medium remaining inside the image forming apparatus when a jam occurs; and an operations display unit configured to provide a display thereon, wherein in a case where the detection unit detects the presence of the recording medium, control is performed to cause the operations display unit to provide a display indicating the presence and prevent a next image forming process from being executed.
