ABSTRACT:
A method for making an electrophotographic developer having developer particles suspended in an insulating carrier liquid comprising reactively producing the developer particles by placing into the carrier liquid at least two substances which are both soluble in the carrier liquid and are insulators relative to the carrier liquid and when in a dissolved state in the carrier liquid precipitate in the carrier liquid to form the developer particles. The developer particles are maintained in the carrier liquid so as to be shielded against oxidation until used as a developer.
