<p>PURPOSE: To obtain a toner for a one- or two-component developer ensuring high image quality and having satisfactory halftone reproducibility and dot reproducibility. CONSTITUTION: This toner consists of two of more kinds of toners different from each other in wt. average particle diameter and each of the toners consists essentially of a bonding resin, a releasing agent, a colorant and charge controlling agent. The particle diameter distribution of each of the toners is defined by the formula [(X-X0 )/X]×100<=25(%) (where X is wt. average particle diameter and X0 is min. observed particle diameter).</p> |
