Abstract

Disclosed is a process for obtaining toners with excellent flow characteristics by accomplishing an oxidation and optional metal chelation of the toner surface. A toner surface oxidation reaction of in-situ prepared toners improves toner flow characteristics. The process effectively removes most of toner surface hydroxy groups and is useful in conjunction with surface grafting or silylation reactions.
