Toner Charging for Two-Component Development Systems

  • Lawrence B. Schein
Part of the Springer Series in Electrophysics book series (SSEP, volume 14)

Abstract

In two component development systems, two powders, toner and carrier, are mixed together (Fig. 2.9). Toner particles have diameters of approximately 10 μm and are blends of polymers and carbon black pigment. Carrier particles have diameters of approximately 200 μm and are composed of magnetically soft cores coated with a thin polymer coating. Contact between the toner and carrier causes charge to be exchanged. Depending on the materials chosen for the toner and carrier coating, the resulting charge on the toner may be positive or negative. This mixture, which has zero net charge, is introduced into cascade or magnetic brush development systems, as described in Chap. 3, where toner particles are attracted to the latent image on the photoreceptor.
