Abstract (en)
Electrostatographic carrier particles possessing all the desirable characteristics for development of negatively charged photoreceptor surfaces are provided by coating carrier cores with polyvinylidene fluoride. After coating, the carrier particles are thermally treated as to provide them with lower negative triboelectric charging values compared with untreated carrier particles.
