Electrostatic charge image developing toner, electrostatic charge image developer, and toner cartridge

An electrostatic charge image developing toner having a surface property index value represented by Formula S of more than 2.8 and 3.5 or less:

• (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)}.

An electrostatic charge image developing toner having 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)}.
