TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE AND ITS PRODUCTION

摘要

PURPOSE:To improve the dispersibility of a magnetic matter by using the toner particles consisting of a polymer obtained by polymerizing a polymerizable monomer in the presence of a titanate type coupling agent. CONSTITUTION:A titanate type coupling agent and inorg. fine powder are mixed, dispersed, or dissolved together with a coloring agent and additives in a polymerizable monomer, whereby a polymerizing composition is obtained and this polymerizing composition is polymerized.
