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.
Claims14
An imaging system comprising
- at least one image forming medium for transferring toner images,
- an endless intermediate medium adapted to be advanced in one direction, to which said toner images are to be transferred,
- at least one image-forming station corresponding to each of said at least one image-forming medium provided where said at least one image-forming medium contacts said endless intermediate medium, said endless intermediate medium being continuously movable at said at least one image-forming station,
- stationary image receiving material,
- an image-transfer station at which said toner images on said endless intermediate medium are transferred to said stationary image receiving material, and
- a first loop-forming means provided between said at least one image-forming station and said image-transfer station and a second loop forming means provided between said image-transfer station and said at least one image-forming station, as considered in the direction of advance of said endless intermediate medium, for periodically enabling stoppage of the advancement of said endless intermediate medium at said image-transfer station.
