PROBLEM TO BE SOLVED: To provide full-color electrophotographic toner which is excellent in rise characteristics of charging, a charging characteristic and transparency, and to provide a toner kit using the toner, an image forming method and device, and a process cartridge. SOLUTION: The full-color electrophotographic toner includes at least a binder resin mainly composed of a polyester resin, a charge control agent including a thiacalixarene compound, and wax (mold-releasing agent) whose viscosity at 90°C is 5-50 centipoise. The toner has a composition formula wherein an absolute value of a difference ¾AVr-AVw¾ between the acid number (AVr) of the binder resin and the acid number (AVw) of the wax satisfies inequalities: 5≤¾AVr-AVw¾≤12. The toner kit using the toner, the full-color image forming method, the full-color image forming device, and the process cartridge are also provided. COPYRIGHT: (C)2010,JPO&INPIT |
