PURPOSE:To prevent the occurrence of the fogging and the splashing of the toner inside the device by adhering magnetic fine particles and organic electrostatically charged fine particles on nonmagnetic toner mother particle. CONSTITUTION:On the surface of nonmagnetic toner mother particles incorporating a binder resin, the electrostatical charged organic fine particles of a quantity of 0.5-6.0wt.% for the toner mother particle are adhered respectively. In this case the magnetic fine particles and electrostatically charged organic fine particles are necessary to be adhered on the surface of the toner mother surface. Thus the toner is easily contacted with the carrier and electrified and the toner density is easily controlled and the occurrence of fogging and the splashing of the toner inside the device are prevented. |
