PROBLEM TO BE SOLVED: To more reliably suppress the void of toner by defining the sticking state between mother particles and an additive agent and more effectively improving the flowability of the toner. SOLUTION: As for a single component toner 5 of one or more colors used for an image forming apparatus and constituted of a large number of toner mother particles 5a and a large number of particles of the additive agent 5b, the inclination of the synchronous distribution where the additive agent sticks to the toner mother particles is set to be 0.3 to 1.3, and also the additive agent isolation ratio of the free additive agent 5b' is set to be≥1%. Consequently, the flowability of the toner is improved, the void is effectively reduced, and good transfer is attained. COPYRIGHT: (C)2004,JPO |
