<p>Toner transporting apparatus for use in forming powder images on an imaging surface. The apparatus comprises a travelling electrostatic wave conveyor (38) for the toner particles (80) for transporting them from a toner supply (78) to an imaging surface (10). The conveyor comprises a linear electrode array (72) consisting of spaced apart electrodes (94, 96, 100, 102) to which a multi-phase a.c. voltage is connected such that adjacent electrodes have phase shifted voltages applied thereto which cooperate to form the travelling wave.</p> |
