TONER FOR DEVELOPING ELECTROSTATIC IMAGE, DEVELOPER FOR ELECTROSTATIC IMAGE, TONER CARTRIDGE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS
摘要:
A toner for developing an electrostatic image, including: toner particles containing at least a binder resin, a release agent, and a colorant; and an external additive having a volume average particle diameter (d) of from 70 nm to 400 nm, a ratio (d/σ) of the volume average particle diameter (d) to a standard deviation (σ) of a volumetric basis particle diameter of from 2.0 to 12, and an average circularity of from 0.5 to 0.9.
