TONER FOR DEVELOPING ELECTROSTATIC LATENT IMAGE

摘要

PURPOSE:To stably ensure high image quality even in development repeated many times. CONSTITUTION:Fine particles having <=50nm particle diameter and fine particles having 100-200nm particle diameter as two kinds of additives are stuck to the surfaces of toner particles to obtain the objective toner for developing an electrostatic latent image. This toner can maintain required electrostatic chargeability and flowability during continuous printing over a long period of time and can prolong the service life of a developer.
