Abstract
An apparatus is provided for transferring a toner image from an endless belt to a receiving material positioned on a flat plate. The toner image is formed by image-forming drums on a part of the belt movable continuously along the drums and is transferred to the receiving material, starting at the leading edge of the toner image and ending at the trailing edge of the toner image. For allowing the latter, an increasable loop is formed in the belt before the image-transfer station and a reducible loop is formed in the belt after the image-transfer station. The loops in the belt are held taut by moving tension rollers in planes forming an acute angle .alpha. with the flat plate, whereby at the image-transfer station the belt forms a constant angle .beta. with the flat plate.
