Buried electrode drum for an electrophotographic print engine |
摘要 |
A buried electrode drum (48) includes a rigid core (10) over which a controlled durometer layer (12) is disposed. On the surface of the controlled durometer layer (12) is disposed a buried electrode layer (14), having electrodes (16) disposed therein along the longitudinal axis of the drum (48). The electrode layer (14) is covered by a controlled resistivity layer (18). The controlled resistivity layer (18) is operable to be contacted on the surface thereof by an electrode (24) to allow a voltage to be transferred to the underlying electrodes (16) and therefrom along the longitudinal axis of the drum (48). Various electrodes can be disposed about the peripheral edge of the drum (48) to allow any pattern to be formed on the surface of the drum (48).
