Toner
Provided is a toner including a toner particle that contains a toner base particle containing a binder resin and a wax, and a coating layer containing a 1,2-polybutadiene resin at the surface of the toner base particle, wherein the coverage ratio of the toner base particle by the coating layer is at least 50%.
1. A toner comprising a toner particle, said toner particle comprising:
a toner base particle containing a binder resin and a wax; and
a coating layer containing a 1,2-polybutadiene resin at the surface of the toner base particle, wherein
the 1,2-polybutadiene resin has a 1,2-syndiotactic structure,
