TONER, DEVELOPER, TONER HOUSING UNIT AND IMAGE FORMING APPARATUS |
| 摘要 |
A toner includes a binder resin; a release agent; and two or more inorganic fine particles as external additives. At least one of the inorganic fine particles is silica. When an ultrasonic oscillation is applied to a dispersion including the toner and a dispersant and a rate of the silica releasing from the toner is 20% based on total silica, an application energy of the ultrasonic oscillation is from 8 to 14 kJ, and from 70 to 130 kJ when the rate of the silica releasing from the toner is 50%. |

1. A toner, comprising:
a toner base particle; a binder resin; a release agent; and two or more inorganic fine particles as external additives, wherein at least one of the inorganic fine particles is silica, and wherein when an ultrasonic oscillation is applied to a dispersion including the toner and a dispersant and a rate of the silica releasing from the toner is 20% based on total silica, an application energy of the ultrasonic oscillation is from 8 to 14 kJ, and from 70 to 130 kJ when the rate of the silica releasing from the toner is 50%. |
