Most carrier cores for electrophotography are made from Cu-Zn or Ni-Zn ferrites. But in recent years, the use of these materials has been restricted by environmental regulations in many countries. In answer, we have developed clean carrier cores from environmentally iiiendly magnetic materials. One such material is magnetite, which we at FDK Corporation mass-produce by using an original product...
