ABSTRACT:
Carrier particles with an average diameter of greater than 44 microns are generated from fly ash, and subsequently admixed with toner compositions enabling developer compositions useful for incorporation into xerographic imaging apparatuses. The aforementioned carrier particles have an apparent density of from about 2.4 to 2.6 grams/cm.sup.3 and a magnetic moment of from about 60 to about 70 electromagnetic units. Images with substantially no background deposits, that is, no dark bands appearing thereon, and substantially no white spots resulted with the aforementioned developer compositions.
