In general, the pre-nip electrode 20 is biased to a much lower potential than the nip electrode 22 or the postnip electrode 24; the electrodes are inserted in a moulded block 16 of resistive material 17, e.g. resistive rubber/plastics or compressed carbon whose thickness is varied so that the resistance between electrodes varies non- linearly with distance from an electrode. Although the block is non-symmetrical about the nip electrode 22, it is of uniform height at any transverse cross-section. Thus the conflicting requirements for the magnitude of the potential is a transfer operation, e.g. for transfer, stripping,  reduction of background, &c. can be met.
