Patent ID: 8041271

Claim:
A system for preventing toner scatter in a laser printer comprising: a laser printer toner cartridge having a hopper section adapted to contain nonmagnetic toner particles and a developing roller adapted to receive non-magnetic toner particles from the hopper section; the hopper section having an orifice adapted to permit flow of the non-magnetic toner particles from the hopper section to the developing roller; a toner regulating member operatively positioned to control flow of the non-magnetic toner particles through the orifice from the hopper section to the developing roller; and, a generally L-shaped shield having a first leg adhered to the toner regulating member, a second leg extending in a direction over a portion of the developing roller and an angle φ defined by and included between the first leg and second leg, wherein the L-shaped shield includes a material having triboelectric properties sufficient to cause the toner particles, when charged, to be repelled from the L-shaped shield; and the shield positioned adjacent the orifice and adapted to inhibit flow of the nonmagnetic toner particles away from the developing roller.
