Abstract
An electrophotographic toner comprising colored particles comprised of inorganic particles is disclosed. The inorganic particles have a saturated moisture content WL at ambient conditions of 10° C. and 20 percent RH of 1.0 to 2.0 percent by weight, a BET value of 70 to 120 m2/g, and a number average primary particle diameter of 10 to 50 nm. Further, the volume average particle diameter of said electrophotographic toner is between 3.0 and 9.0 μm.
