ONE-COMPONENT TONER FOR NONMAGNETIC DEVELOPING SYSTEM

摘要

PURPOSE:To provide a one-component toner for a nonmagnetic developing system excellent in flowability, ensuring a slight change of image density and hardly causing fog. CONSTITUTION:A silicon dioxide-based additive is stuck to the surfaces of toner particles. The absolute value of the extent of electrostatic charge of the toner particles is >=25muC/g, that of the additive is <=500muC/g and the additive is electrostatically charged to the same polarity as the toner particles. The objective one-component toner for a nonmagnetic developing system is obtd.
