CARRIER FOR ELECTROPHOTOGRAPHY AND DEVELOPER USING THE SAME FOR ELECTROPHOTOGRAPHY

摘要

Disclosed are a carrier for electrophotography and a developing agent using the same. The carrier includes a carrier core material with magnetism and a high-molecular-weight polyethylene resin that coats the surface of the carrier core material, wherein the surface of the high-molecular-weight polyethylene resin coating the surface of the carrier core material is coated with a resin layer having an ability to control electric charge and a thickness of 0.01-2 mu m or with a particle layer having an ability to control electric charge and a thickness of 0.01-2 mu m,. The carrier for electrophotography and the developing agent using the same allow free control of its electrification polarity and free adjustment of the amount of electrification, taking advantage of excellent properties of the carrier having a polyolefin-based resin coat.
