TWO-COMPONENT COLOR DEVELOPER

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing toner such that a zirconium organic metal compound is incorporated as a negative electrification controlling agent into color toner so as to improve the electrification rising property of the toner and that the by-product produced in the manufacture of the toner is reused so as to improve the yield. SOLUTION: A zirconium organic metal compound expressed by general formula (I) is incorporated as a negative electrification controlling agent into the toner to improve the rising characteristics of the toner. The by-product produced in the classifying process of the toner is reused by adding by 1 to 30 wt.% to the source material of the toner to improve the production yield and to decrease the cost.
