ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER

摘要

PURPOSE:To provide a toner excellent in dispersibility of a colorant and having stable image characteristics. CONSTITUTION:In the toner obtained by polymerizing a polymerizable monomer mixed solution containing at least a colorant such as carbon black, the toner is improved in charge stability and shows the stable image characteristics even in the case of continuous printing or environmental change by making the max. length of the secondary aggregate of the colorant particle dispersed in the toner below the half of the particle diameter of the toner.
