Positive electrified charge control agent and charge control method of toner using it

摘要

A positive electrified charge control agent comprises a silicon complex compound represented by the following chemical formula (1)
(in the formula (1), [A] - is a sulfate anion). A positive electrified toner for developing an electrostatic image comprises the positive electrified charge control agent. A charge control method of the positive electrified toner for developing the electrostatic image comprises a step for making the toner positively electrified by friction.
