ABSTRACT:
Toner images are transferred in registry to a receiving sheet held on a transfer drum which drum has one or more layers which varies in resistivity. To offset difficulties in initial securing of the sheet to the drum, a transfer field is not applied as the leading edge of the sheet attaches to the drum. The transfer field is applied after a predetermined delay, which delay is varied as a function of the resistance of the drum.
