摘要： A fold-enforcing assembly includes a fold-enforcing device, a moving device to move the fold-enforcing device in a direction of a fold of a sheet bundle, and control circuitry. The fold-enforcing device includes a pressing member pair to nip and press the fold of the sheet bundle in a direction of thickness, a pressing mechanism to pressurize and depressurize the pressing member pair, and a driver to drive the pressing mechanism. Controlled by the control circuitry, the moving device moves the fold-enforcing device in accordance with a size of the sheet bundle in the direction of the fold; pressing mechanism pressurizes the pressing member pair to press a first end portion of the sheet bundle in the direction of the fold; the moving device moves the fold-enforcing device to a second end portion of the sheet bundle; and pressing mechanism depressurizes the pressing member pair in the second end portion.

摘要： A sheet conveying device, which is included in an image forming apparatus, includes a first guide, a second guide, and a lever. The first guide is fixedly disposed to the sheet conveying device. The second guide is disposed opposite the first guide and defining a sheet conveyance passage with the first guide and is configured to rotate about a support shaft thereof operable to open and close the sheet conveyance passage. The lever is configured to rotate about a rotation shaft thereof operable to rotate the second guide. The second guide is configured to change from a closed state in which the sheet conveyance passage is closed to an open state in which the sheet conveyance passage is open, after an angle of rotation of the lever exceeds a threshold value.

摘要： A sheet feeding device feeds a sheet in a feed direction. The sheet feeding device includes a loading portion, a feeler, and a first detection sensor. The sheet is to be placed on the loading portion. The feeler rotates from a reference position to a pushed position around a support shaft in response to a push by a downstream end of the sheet, which is placed on the loading portion, in the feeding direction. The first detection sensor detects a rotation of the feeler from one of the reference position and the pushed position to the other of the reference position and the pushed position. The loading portion includes a second detection sensor to detect a state in which the sheet is placed on the loading portion.
