Abstract
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.
Claims21
A particle comprised of at least a binder, wherein the particle includes on an external surface thereof a coating comprised of a doped conductive polymer material on or in a particle matrix.
A method of forming a particle, comprising forming core particles comprised of binder, incorporating a doped conductive polymer material onto and/or into at least one external additive particle, and applying the at least one external additive particle onto an external surface of the core particles.
A method of making a particle, comprising forming a core particle material including binder, subjecting the core particle material to size reduction to form core particles, and introducing a doped conductive polymer material during the size reducing step so as to form a coating of the doped conductive polymer material on an external surface of the core particles.
