Abstract
A magnetic brush development system including a spatially programmable electrode-type applicator roll for developing latent electrostatic images carried by an imaging surface of an electrostatic processor as the imaging surface moves through a development zone which is subjected to a substantially stationary, locally generated electrostatic field having a generally uniform intensity widthwise of the imaging surface and a preselected, non-uniform intensity lengthwise of the imaging surface.
