Abstract:
Provided is a toner containing: a toner particle containing a binder resin; and an inorganic particle, wherein the inorganic particle contains a silicon oxide particle with a number-average particle diameter (D1) from 50 nm to 300 nm and a strontium titanate particle with a number-average particle diameter (D1) from 10 nm to 60 nm, the content of the silicon oxide particle is from 0.5 to 15.0 mass parts per 100 mass parts of the toner particle, the content of the strontium titanate particle is from 0.02 to 5.00 times the content of the silicon oxide particle, and in dielectric constant measurement at 25° C. and 1 MHz, the dielectric constant of the silicon oxide particle is from 1.0 pF/m to 20.0 pF/m, and the dielectric constant of the strontium titanate is from 25.0 pF/m to 100.0 pF/m.
