ABSTRACT:
A toner density controller for determining the density of a development material in a magnetic brush assembly of an electrostatic copier is disclosed. Means is provided for imposing a charge on the toner density controller which is opposite in charge to that of the toner particles of the development material. In this way, the toner particles, particularly fines, are repelled from the toner density controller to eliminate interference with the functioning of the controller.
