Abstract: An image forming apparatus to which a first feeding device which does not notify abnormal sheet feeding or a second feeding device which notifies the abnormal sheet feeding is connectable includes a sheet receiving portion, a sheet detector, an image forming unit, and a controller. In a case that the first feeding device is connected to the image forming apparatus, the controller discriminates that the abnormal sheet feeding occurs in the first feeding device when the detector does not detect the sheet at first timing. In a case that the second feeding device is connected to the image forming apparatus, the controller discriminates that the abnormal sheet feeding occurs at the sheet receiving portion when the detector does not detect the sheet at second timing and notification of the abnormal sheet feeding is not provided from the second feeding device.

The multiple position detectors are aligned along a sheet conveying direction and configured to detect a side end of a sheet. The position corrector is configured to convey the sheet and correct a position of the sheet based on a positional deviation amount of the sheet, obtained by a detection result of the multiple position detectors. The positional deviation amount of the sheet is obtained by an extreme downstream position detector in the sheet conveying direction, of the multiple position detectors.

Abstract: The present application discloses a post-processing apparatus which performs a predetermined process after an image formation process performed by an image formation apparatus. The post-processing apparatus includes an ejection tray, which supports a sheet stack, in which sheets are stacked, and a curl prevention portion including a first tray cursor, which abuts an upper surface of the sheet stack on the ejection tray to prevent the sheet stack from curling. The curl prevention portion includes an angle changer, which changes an inclination angle of the first tray cursor with respect to the ejection tray. The angle changer sets the inclination angle to a first value when a number of sheets is a first number. The angle changer sets the inclination angle to a second value different from the first value when the number of the sheets is a second number different from the first number.

Abstract: A device for treating substrates has a separation system, with which processed substrates can be separated into one or more waste parts and at least one blank.
