ABSTRACT:
An apparatus for developing electrostatic latent images includes an applicator for applying a developer, containing a high concentration of developer particles, uniformly over both the image and non-image areas of a latent image bearing surface, and a developing device including a liquid reservoir and an elastic roller including a core shaft, a porous elastic inner layer on the core shaft, and a flexible and permeable sleeve-like net covering the inner layer. Liquid from the reservoir is applied by the roller to the image bearing surface to remove developer particles not attracted thereto by coulomb force to thereby form the developed image. Marginal effect in the developed image is eliminated by making at least one of the inner layer or net electrically conductive.
