Abstract
The triboelectric harmony of reconditioned electrostatographic cartridges may be reestablished by coating a flexible charge blade with a quantity of dry, particulate electrically conductive material, for example, particulate carbon black or graphite. Preferably, the electrically conductive material is carbon black having an average particle diameter of between about 15 to about 95 nm. The surface-coated charge blade will most preferably exhibit a surface resistivity of less than about 1.times.10.sup.7 .OMEGA./cm (i.e., between 0 to about 1.times.10.sup.7 .OMEGA./cm), more preferably between about 1.times.10.sup.5 to about 7.5.times.10.sup.5 .OMEGA./cm.
