摘要:
A method of preparing carrier for electrophotography, which includes a core material and a coating material layer formed on the surface of the core material, including coating a coating material of the coating material layer on the core material; and burning the coating material by an induction heater, wherein the induction heater applies an alternative current to parallely-located plural coil circuits including a conductive wire including the shape of a coil to generate a magnetic line changing its direction and intensity for inductively heating the core material to heat the coating material.
