摘要：
An electrostatic charge image developing toner has a surface property index value represented by Formula S of 2.0 to 2.8, an electrostatic charge image developing toner has a surface property index value represented by Formula S of more than 2.8 and 3.5 or less, and an electrostatic charge image developing toner has a surface property index value represented by Formula S of more than 1.0 and less than 2.0 and a calculated value of a specific surface area in Formula S of 0.70 to 1.3: (Surface property index value)=(Measured value of specific surface area)/(Calculated value of specific surface area) Formula S wherein (Calculated value of specific surface area)=(Sum of surface areas calculated from equivalent circle diameters of 4,500 toner particles in flow type particle image analysis)/{((Specific gravity of toner)×(Sum of volumes calculated from equivalent circle diameters of 4,500 toner particles in flow type particle image analysis)}.
