Toner is powdery material used for copy machine, beam printer
and fax machine and it is exhausted material to be printed and
adhered to paper. Magnetite for toner is one of the core ingredients
for toner which is black crystalline particle with resin. Its
average radius is 0.2~0.3§. It requires highly careful quality
control as a critical factor that determines toner¡¯s main attributes
such as clearness, consumed quantity and efficiency of copying.
Saehan Media Co., Ltd started development of magnetite for toner
in 2000 based on composition technology of Iron Oxide for audio,
video tape and quality system. It succeeded in commercializing
magnetite for toner in 2001 and now is extending sales in the
world diversifying products of magnetite for toner. |

SMT-01S is used to produce toner for laser printer.
It generates high resolution due to its low coercive force
and even magnetism distribution. |

SMT-02H is high coercive force magnetic body and it
is used to produce toner for printers which is 50ppm and
faster. High coercive force allows toner to be developed
stably even under magnetic brush spinning fast and sensitized
drum. |
