1528835 Transferring electrostatic or toner images OCE-VAN DER GRINTEN NV 5 March 1976 [11 March 1975] 08990/76 Heading B6C In an indirect electrophotographic copying apparatus in which either an electrostatic image or a toner image is transferred from a moving image carrying surface to a moving surface of an intermediate support, the two surfaces are driven at slightly different speeds, e.g. 1-3% difference, and are urged into pressure contact only when images are to be transferred during which time the drive of one surface is dominated by the drive of the other surface through one surface constraining the other surface by friction at the place of pressure contact to run at the same speed.
