Abstract: An image forming system includes a sheet conveyance unit, an image forming unit, a fixing unit and a controller. The sheet conveyance unit conveys continuous paper. The image forming unit forms an image on the continuous paper. The fixing unit fixes the image formed on the continuous paper. The controller controls an image forming operation performed by the sheet conveyance unit, the image forming unit and the fixing unit. In a case where a waste paper reduction mode is selected, the controller controls the sheet conveyance unit to stop conveying the continuous paper so that a bottom end of a last image on the continuous paper be at a second stop position on an upper-stream side of a first stop position after the bottom end of the last image passes the fixing unit when ending the image forming operation.
