An external additives for electrophtographic toner comprising finely
divided oxide particulate including a silicon compound and a compound for
doping said oxide particulate, wherein particle diameter of the primary
particle of said finely divided oxide particulate is in the range of 30
nm to 150 nm, and the primary particle of said finely divided oxide
particles is substantially spherical shape having the roundness in the
range of 0.95 to 0.996, is provided. And this external additives is
capable of evading from the embedding of external additives into toner
even if after the toner is held in the storage under the condition of
high temperature and high humidity, thereby the additives is capable of
showing sufficient functions as fluidizing agent and charge supplement
agent, and is capable of inhibiting an abnormal charge elevation even
after being stored under the low temperature and low humidity.
