Abstract
Apparatus and method for developing electrographically formed electrostatic images. Background development and 'flaming' are minimized by applying composite D.C. and A.C. signals to a development electrode in a magnetic brush. The DC signal level is selected to minimize background development and the AC signal is chosen to minimize flaming.
