Abstract
A sheet processing apparatus for folding a sheet bundle at a predetermined position includes paired rotating bodies for folding the sheet bundle having nip portions, a pressing device for pressing the predetermined position of the sheet bundle into the nip portions of the paired rotating bodies, and a device connected to the paired rotation bodies for providing rotation to the paired rotating bodies. A pulling force of the rotating bodies to pull the sheet bundle pressed into the nip portions of the rotating bodies has an amount which does not separate a sheet of the sheet bundle contacting the rotating bodies from the subsequent sheets in the sheet bundle when pulling the sheet bundle.
