PROBLEM TO BE SOLVED: To provide a toner whose electrification is effectively improved by considering the sticking state of additive agent to a mother particle. SOLUTION: The toner T contains at least an electrifying additive agent as an additive agent 19. The additive agent isolation ratio of the electrifying additive agent is set to be 0.5 to 8%. Thus the triboelectrification between the free additive agent of the electrifying additive agent and the toner mother particles is appropriately performed. Consequently, the electrification of the toner T is more appropriately adjusted, and the toner is stably electrified. COPYRIGHT: (C)2004,JPO |
