Abstract
An electrostatic charge image developing toner includes a binder resin that contains an amorphous polyester resin and a colorant. The toner satisfies the following expressions: 20 μS/cm≦ρ≦150 μS/cm, and 0.01%<Cm/(Cc+Co)×100<0.1%, where ρ represents the conductivity of a supernatant solution when 0.1 g of the toner is dissolved in 30 ml of tetrahydrofuran, Cm represents the content (% by mass) of metal elements Al, Mg, and Fe, Cc represents the content (% by mass) of carbon, and Co represents the content (% by mass) of oxygen.
