Abstract
A sheet processing apparatus includes a pushing member, a drive device, a first conveyance unit, a second conveyance unit provided on a downstream side of the first conveyance unit, a first detection unit, a second detection unit, and a control unit. The drive device moves the pushing member to push a portion of a sheet bundle to fold the sheet bundle. The first conveyance unit uses a roller pair to convey the folded sheet bundle folded. The second conveyance unit conveys the sheet bundle. The first detection unit detects an amount by which the pushing member is moved by the drive device. The second detection unit detects an amount by which the sheet bundle is conveyed by the first conveyance unit. The control unit separates the roller pair based on the amounts detected by the first and second detection units.
