<p>PROBLEM TO BE SOLVED: To reduce residual toner left after transfer on a photoreceptor to little. SOLUTION: As for the toner used for an image forming apparatus provided with a photoreceptor and an intermediate transfer body whose circumferential speed is different from that of the photoreceptor, and as to the toner measured by a particle analyzing method for guiding the toner particles in a plasma, detecting the emission spectrum, detecting the component amount from the emitted light intensity and then detecting whether the additive agent is synchronized with the toner or isolated from the toner based on the effect whether or not the light is simultaneously emitted, the ratio of the toner with which charging controlling agent is not synchronized is controlled to be <=2%.</p> |
