    摘要: Particles, preferably toner particles comprised of at least binder and colorant, are described that include a doped conductive polymer material as a surface additive on the external surface of the particle. The presence of the doped external conductive polymer material enables the particles to retain a substantially uniform charge distribution over the surface of the particles over time, and also enables appropriate control over the triboelectric (tribo) properties of a developer. Also described are developers comprised of such particles in admixture with carrier particles, and methods of making the particles and developers.
