ABSTRACT:
An apparatus which reduces the scattering of charged particles from a housing storing a supply thereof in a reproducing machine having photoconductive member with an image voltage level recorded on a portion thereof. A particle holder is electrically biased to a voltage level different than that of the image voltage recorded on the photoconductive member. In this way, an electrical field is formed between the photoconductive member and the particle holder which repels or attracts the charged particles therefrom. The particle holder is readily removable from the reproducing machine so as to facilitate the periodic cleaning of charged particles therefrom.
