Provided is a toner for developing an electrostatic image capable of suppressing fluctuations in image density even when used over time. Toner particles containing at least a binder resin, a release agent, and a colorant, a volume average particle diameter d of 70 nm to 400 nm, and a volume average particle diameter d with respect to a standard deviation σ of a volume-based particle diameter. And an external additive having a ratio (d / σ) of 2.0 or more and 12 or less and an average circularity of 0.5 or more and 0.9 or less. [Selection figure] None |
