| titleOfInvention | Manufacturing method of ferrite carrier and product |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a ferrite carrier (Ferrtie Carrier), and a product thereof. In particular, a magnesium-copper-zinc ferrite-based material is formed on the surface of a ferrite core to form a uniform coating film to improve the carrier surface. The present invention relates to a method for manufacturing a ferrite carrier having a coating film on a core surface thereof and a product thereof. The developer used in the conventional magnetic brush method is a material of a carrier, which is a material which strongly magnetizes in a direction by a magnetic field, When the electrostatic charge phase is connected with electric charges, an electrostatic charge is short-circuited, and the short-circuiting phenomenon forms an insulating resin coating layer on the surface of the magnetic particles. When the insulating carrier is used, toner particles are formed on the surface of the carrier particles. Attached to contaminate the copying surface, and because the frictional charging characteristics of the carrier and toner are different, Its durability is reduced, its service life is shortened, and there are various problems in that high-speed copying is not possible due to the above problems even at high-speed electronic copying.n n n The present invention has been made in view of the above-described problems of the prior art, and has been devised to solve the problem. The coating or peeling of the coating film does not occur due to the interaction between carrier particles with a magnesium-copper-zinc ferrite-based material. The particles of the carrier are spherical so as not to provide a feature of providing a core having a good smoothness of the surface thereof. |
