ABSTRACT:
In a copying apparatus of the type employing a moving image-carrying belt from which an image is transferred to an intermediate support during the action of a device for pressing the belt against and advancing it with intermediate support, which is moved at a speed slightly lower than the speed at which the belt is driven, lengths of the belt leading to and from the belt pressing device are engaged by respective floating rollers which apply first and second forces tensioning the belt. The second tensioning force is kept greater than the first, thus acting when the pressing device is inactive to displace upward the belt lead to the pressing device, and an arrest device limits the upward displacement.
