NONMAGNETIC SINGLE-COMPONENT COLOR TONER

摘要

PROBLEM TO BE SOLVED: To provide a nonmagnetic single-component color toner, capable of stabilizing image quality over a long periods of time, without lowering the initial printing quality. SOLUTION: The nonmagnetic single-component color toner contains resin particles, consisting essentially of a bonding resin and a colorant and two additives different from each other in polarity added to the surfaces of the resin particles. The average particle diameter of the primary particles of each of the two additives is >=30 nm.
