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 .mu.m to 12.0 .mu.m. The metallic-compound fine particles are conductive metallic-compound fine particles having a specific surface area (cm.sup.2/cm.sup.3) of 5.times.10.sup.5 to 100.times.10.sup.5; a medium diameter (D.sub.50) of 0.4 .mu.m to 4.0 .mu.m with respect to a volume-based particle diameter distribution, the medium diameter (D.sub.50) being smaller than the weight average particle diameter of the toner; and a 90% particle diameter D.sub.90 of 6.0 .mu.m or less with respect to a volume-based particle diameter.
