Carrier for electrophotography, method for producing the same carrier, and developing agent for electrophotography using same

摘要

Disclosed are a carrier for electrophotography, a method for producing the same carrier, 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 an electric charge and a thickness of 0.01-2 mum or with a particle layer having an ability to control an electric charge and a thickness of 0.01-2 mum.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.
