Abstract
There is described a novel toner for developing static latent image, of which relaxation time is adjusted to 5 through 20 milliseconds at 100 KHz of frequency. The toner is perfectly compatible with cleaning requirements, and thus, fusion or filming of toner onto the surface of photoreceptor is secured prevented, so that clear and distinct image can be securely produced for a long time.
