Abstract
PURPOSE: To easily remove a toner not containing a magnetic powder, by providing means for preparing particles containing a magnetic powder and a magnet for recovering a magnetic toner.
CONSTITUTION: A fluid magnetic material in raw material tank 4 is finely divided and sprayed in drying chamber 1. The dried toner particles are drawn toward cyclone 8 in suspension. At that time the toner particles containing a magnetic powder is attracted to electromagnet 6, while the particles not containing the magnetic powder enter cyclone 8, and are taken out from nonmagnetic toner outlet 9. The magnetic toner attracted to magnet 6 is recovered by cutting off its power supply, thus permitting the toner not containing the magnetic powder to be easily removed. Alternatively, use of methods other than the spray drying method permits similar effects to be obtained.
