| titleOfInvention | Method for producing magnetic toner |
| abstract | An object of the present invention is to suppress exposure of magnetic powder and wax, to be excellent in toner lot quality stability, to be usable in various types of reproduction cartridges, and to be stable in image density, OPC filming resistance, and environmental stability. Provided is a method for efficiently producing a magnetic toner having excellent properties. The content of a magnetic powder surface-treated with a thermoplastic resin, a hydrophobic silica powder, a wax and a charge control agent, and the surface of the magnetic powder surface-treated with the hydrophobic silica powder is 30 to 70% by mass. The kneaded material is kneaded using a batch type closed kneader, then cooled and crushed to obtain a kneaded chip, and then this kneaded chip is kneaded again using the batch type closed kneader, and then cooled, The toner base particles are prepared by pulverization and classification, and a magnetic toner containing the toner base particles is manufactured.
