Abstract: There is provided a sheet processing apparatus that is capable of preventing sheets conveyed to the sheet processing apparatus from being skewed, wrinkled, damaged, or jammed, and prevent sheets stored in the sheet processing apparatus from being misaligned. The sheet processing apparatus receives a sheet discharged from an image forming apparatus comprising fixing rollers that hold and convey a sheet on which is formed an image at a first conveying speed and with a first conveying force, discharge rollers disposed downstream of the fixing rollers in a sheet conveying direction, for conveying the sheet at a second conveying speed higher than the first conveying speed and with a second conveying force smaller than the first conveying force, and a controller that determines whether a trailing end of the sheet is released from the fixing rollers.

Abstract: An image forming apparatus has an image forming device, a first discharge tray for receiving a sheet on which an image was formed, a conveyer for selectively transporting the sheet on which the image was formed by the image forming device to one of a first discharge tray and a sheet processing device, and a controller for controlling a power source so as not to supply electric power to the sheet processing device and the conveyer to transport the sheet to the first discharge tray when discharging the sheet to the first discharge tray, and controlling the power source to supply power to the sheet processing device and the conveyer to transport the sheet to the sheet processing device when discharging the sheet to a second discharge tray provided on the sheet processing device.

Abstract: A sheet treating apparatus to be connected to an image forming apparatus, which has a sheet guide portion which selectively guides a sheet to a sheet stacking portion or a sheet treating portion and, in a state in which a power supply of the sheet treating apparatus is turned off, the sheet guide portion guides a sheet to the sheet stacking portion such that a sheet delivered from the image forming apparatus can be stacked even if the power supply of the sheet treating apparatus is turned off. Moreover, a sheet can be stacked on the sheet stacking portion without using a transporting drive force of the sheet treating apparatus.
