Drive mechanism for an electrographic transfer roller apparatus wherein potential degradation of a transferred image is substantially prevented by eliminating relative movement between a receiver member supported by such apparatus and a transferable image carrying dielectric member in contact in a transfer zone. In the drive mechanism, a dielectric member is supported and moved through a transfer zone. A selective drive for the transfer roller is coupled to the transfer roller when a receiver member, supported by the transfer roller, is out of the transfer zone and decoupled from the transfer roller when the attached receiver member is in contact with the dielectric member in the transfer zone. Therefore, when the receiver member and the moving dielectric member are in contact in the transfer zone, drive is imparted only through such contact and the receiver member and dielectric member move at the same peripheral surface speed.
