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. In the sheet processing apparatus, sheet discharge rollers convey the received sheet, and a controller sets the conveying speed of the sheet discharge rollers to the first conveying speed while the sheet is being conveyed by all of the fixing rollers, the discharge rollers, and the sheet discharge rollers, and sets the conveying speed of the sheet discharge rollers to the second conveying speed after the controller determines that the trailing end of the sheet is released from the fixing rollers.
