Abstract
A sheet processing apparatus capable of reliably superposing a sheet to be buffered and a following sheet in a manner displaced by an allowable displacement amount, thereby making it possible to suppress generation of misalignment. A sheet discharged from an image forming apparatus is temporarily held back, and a following sheet is superposed on the held-back sheet in a state displaced in a conveying direction. A length in the conveying direction of the sheet to be held back and a length in the conveying direction of a sheet bundle of the superposed sheets are measured. A displacement amount provided between the superposed sheets, computed as a difference between the measured length of the sheet and the measured length of the sheet bundle, is adjusted such that the displacement amount becomes a target displacement amount.
