Abstract
A toner including: a toner particle including a toner base particle containing a binder resin, and an organosilicon condensate present on a surface of the toner base particle, wherein a charge attenuation constant of the toner is 3.5×10−3 or more to 1.0×100 or less.
Claims7
A toner comprising a toner particle, the toner particle comprising:
- a toner base particle containing a binder resin;
- an organosilicon condensate formed on a surface of the toner base particle;
- and
- an inorganic fine particle disposed between the organosilicon condensate and the toner base particle, wherein
- the toner particle has a toner particle surface comprising the organosilicon condensate and the inorganic fine particle, the toner particle surface being formed by condensation of an organosilicon compound with the inorganic fine particle,
- the toner has a charge attenuation constant of 3.5×10−3 to 1.0×100, and
- the inorganic fine particle is an alumina fine particle or a strontium titanate fine particle.
