Abstract
A copying apparatus provided with a system for transferring electrostatic or powder images from a moving image supplying surface to a moving intermediate surface for temporary retention on the latter, wherein the respective supports of the surfaces are pressed together during image transfer and are kept apart at other times, is made with an arrangement which assures synchronized movement of the two surfaces for image transfer by driving the supports at slightly different speeds yet causing one of them to be driven by friction with the other, precisely at its speed, while and at the location where the surfaces are pressed together for image transfer.
