ABSTRACT:
A decrease in the ability of an electrostatic charge controlling brush to place a uniformly distributed charge on charge-retaining material is precluded by limiting the amount of current available to the brush to less than the magnitude necessary to melt the free ends or tips of bristles forming a portion of the brush to thereby avoid changes in bristle tip shape and the attendant reduction in ability to produce a particular electrostatic charge level that would result from such bristle melting.
