An apparatus which develops an electrostatic latent image with electrostatically charged particles. The apparatus produces a magnetic field which forms a brush-like array of charged particles. A development electrode is operatively associated with the magnetic field to suppress the effect of local contrast enhancement.

DETAILED DESCRIPTION Briefly stated and in accordance with the present invention, there is provided an apparatus for developing an electrostatic latent image with electrostatically charged particles.
This is achieved by the apparatus of the present invention which includes magnetic field producing means and development electrode means.
In operation, the magnetic field producing means is positioned closely adjacent to the latent image.
The magnetic field producing means forms a brush-like array of charged particles contacting the latent image.
Operatively associated with the magnetic field producing means is development electrode means.
The development electrode means is closely spaced to the latent image so as to suppress the effects of local contrast .
