Abstract
An electrostatic charge image developing toner set includes an electrostatic charge image developing black toner that includes black toner particles including a black colorant, a binder resin, and a release agent, and inorganic particles having an average particle diameter of 50 nm to 300 nm; and an electrostatic charge image developing color toner that includes color toner particles including a color colorant, a binder resin, and a release agent, and inorganic particles having an average particle diameter of 50 nm to 300 nm, wherein a proportion of the release agent exposed to a surface of the color toner particles is greater than a proportion of the release agent exposed to a surface of the black toner particles.
