Abstract

1526166 Electrophotographic carrier particles RICOH CO Ltd 1 June 1977 [7 June 1976] 23082/77 Heading B2E [Also in Division G2] Electrophotographic carrier particles comprise magnetic granules, e.g. of Fe, Co, Ni, alloys thereof magnetite and ferrite having a coating desired from polybutene of viscosity 1,500-6000 cps. A preferred coating weight is 0.05 to 1% on granules of size 100-300 mesh (50-150 microns).
