Powdery developing material for electrophotographic reproduction |
摘要 |
A dry developing powder composition particularly suited for use in electrophotographic reproduction which comprises a magnetic toner of 35 to 50 microns in average particle size mixed with a non-magnetic toner of 5 to 30 microns in average particle size. The amount of the magnetic toner used is within the range of 85 to 98% by weight relative to the total weight of the composition and the amount of the non-magnetic toner used is within the range of 2 to 15% by weight relative to the total weight of the composition.
