ABSTRACT:
The present invention relates to a magnetic toner composition, and more particularly to a magnetic toner composition having an improved chargeability and excellent uniform chargeability, and that is capable of reducing a difference in electrostatic charge between a toner remaining in a cartridge or in a developing unit and that of a newly supplied toner. A magnetic toner composition of the present invention comprises magnetic toner particulate comprising a binder resin and a magnetic substance, a conductive fine powder having a specific surface area of 30 to 300 m2/g, a hydrophobic silica having a specific surface area of 100 to 240 m2/g, and an inorganic fine powder having an average diameter of 0.1 to 4.O μm.
