Carrier Cores
Carrier cores are used to transport toners as part of the electrophotographic
process employed in full colour printers, black-and-white printers and copying
machines. The carrier core grade products are developed to gain better
performance and cost-effectiveness from the developer, without endangering the
environment.
Application
Examples
Carriers, polymer-coated
carrier cores, are used to transport toners as a part of the electrophotographic
process. The carriers charge the toners and transport them to the photoreceptor
on which a latent electrostatic image has previously been formed. The toners
detach from the carriers due to a combination of impact and electrostatic
forces. Once the toners have transferred to the photoreceptor, the carriers
return to the developer container for more toner particles.
Features and Benefits
The carrier cores consist either of magnetite or pure iron. Certain grades of
iron powders may be developed to deliver important carrier core characteristics
such as soft magnetic properties, particle size distributions, low density, good
flow, powder morphology and electrical qualities.
