Abstract
In an electrostatic copying apparatus, background toner particle removal is enhanced by employing a corona emission device between a development station and a background toner removal station. The corona emissions are such as to substantially reduce the background residual potential on a photoconductor and ensure that all background particles on the photoconductor are of a polarity opposite to the polarity of the charge on the latent image whereby toner particles may be more easily removed from the photoconductor surface.
