ABSTRACT:
A toner exhibits excellent image characteristics, and also has an excellent charging property even if the toner is used in a cleaning-simultaneous-with-developing system having a direct injection charging mechanism. The toner includes toner particles and non-magnetic metallic-compound fine particles. The weight average particle diameter of the toner is 3.0 μm to 12.0 μm. The metallic-compound fine particles are conductive metallic-compound fine particles having a specific surface area (cm2/cm3) of 5×105to 100×105; a medium diameter (D50) of 0.4 μm to 4.0 μm with respect to a volume-based particle diameter distribution, the medium diameter (D50) being smaller than the weight average particle diameter of the toner; and a 90% particle diameter D90of 6.0 μm or less with respect to a volume-based particle diameter.
