发明名称 MAGNETIC TONER
摘要 Provided is a magnetic toner which has excellent fixedness at low temperature and excellent developing property, antifogging property, and transfer efficiency even when the toner is used for a long-term period. The magnetic toner of the present invention comprises: a magnetic toner particle which include a settlement resin and a magnetic substance; an inorganic fine particle ″a″; and an organic-inorganic complex fine particle. The magnetic toner has real density greater than or equal to 1.40 g/cm^3 and less than or equal to 1.70 g/cm^3 and saturation magnetization greater than or equal to 10 Am^2/kg and less than or equal to 20 Am^2/kg under magnetic field of 796 kA/m. The inorganic fine particle ″a″ is a metal oxide having volume resistivity greater than or equal to 1.0×10^3 Ω·cm and less than or equal to 1.0×10^8 Ω·cm.
