Abstract
Photoconductive particles are prepared by the reaction of a water-soluble metal salt with an ion exchange resin having an anion which reacts with the metal ion of the water-soluble metal salt to produce a water insoluble metal compound and the deposition of the water insoluble metal compound resulting from the reaction on the surface of the photoconductive particles.
