DUAL POLARITY ELECTROSTATIC BRUSH CLEANER

PROBLEM TO BE SOLVED: To remove charged particles without increasing a size and cost. SOLUTION: The brush cleaner has a cleaner brush 100 for removing the residual toner particles sticking to an outer surface of a photoconductive drum 100 of an electrophotographic printing machine, a toner removing roll 110 for removing the residual toner particles sticking to the cleaner brush 100 and a scraper blade 112 for removing the residual toner particles from the toner removing roll 110. The cleaner brush 100 includes a conductive core and is segmented to brush segments 120, 121, 122, and 123. Brush pile fibers 130 connected to the core by the brush segments 120, 121, 122, and 123 are biased to both of a negative and positive. COPYRIGHT: (C)2005,JPO&NCIPI
