NONMAGNETIC ONE-COMPONENT COLOR TONER

摘要

PROBLEM TO BE SOLVED: To obtain a nonmagnetic one-component full-color toner containing a uniformly and finely dispersed releasing agent, having an anti-offsetting effect and excellent in durability. SOLUTION: At least a bonding resin, colorants and a releasing agent are melted and kneaded to obtain the objective electrophotographic nonmagnetic one-component full-color toner. The releasing agent is incompatible with the bonding resin and the releasing agent content of the toner does not exceed the total amount of the releasing agent which can be absorbed in releasing agent absorbing materials in the toner. The amount of the releasing agent which can be absorbed is regulated by adding a releasing agent absorbing material other than the colorants and an electrostatic charge controlling agent.
