Abstract: Development electrode apparatus is provided in accordance with the teachings of the present invention wherein at least two development electrodes are employed at a developing station in electrophotographic apparatus. The first development electrode presented to a latent electrostatic image undergoing development displays characteristics which are optimum for high rates of developer flow and hence only reduced development of portions of a latent electrostatic image exhibiting low charge densities and extended areas is achieved but may be accompanied by optimum cleaning. The second development electrode presented to the latent electrostatic image to be developed displays characteristics which are optimized to complete low contrast and extended area development; however, as the majority of developer material is removed, no inhibition of the developer flow occurs at said second development electrode.
