Patent ID: 7899384

Claim:
A device for reducing the buildup of particulate contamination on elements within an image forming apparatus, the device comprising: a photoconductive element having a surface, wherein said surface of said photoconductive element has a charged state at a first voltage level V 1 and discharged state at a second voltage level V 2 ; a charging element positioned against said photoconductive element for charging said photoconductive element to said charged state; and a conductive polymer cleaner blade for said photoconductive element, said cleaner blade having a resistance of about 2.75×10 8 to about 4.25×10 8 ohms, including all ranges and values therebetween, and an edge in contact with said surface of said photoconductive element with said edge of said cleaner blade having a continuously applied third voltage level V 3 wherein |V 1 |>|V 2 |>|V 3 | and said particulate is charged by said edge of said cleaner blade such that said particulate is repelled by said charging element.
