摘要：
An electrostatic latent image developing toner that is made by adding electrically conductive powder as an external additive to toner particles comprising a binder resin and a colorant, wherein the liberation rate of the electrically conductive powder is from 50 to 90%; and the number average particle size distribution index G of the toner particles, which is represented by the following formula (1), is 1.20 or less. particle size distribution index G=D50/D16 Formula (1)And an electrostatic latent image developing toner that is made by adding a metal oxide as an external additive to toner particles comprising a binder resin and a colorant, wherein the liberation rate of the metal oxide is from 30 to 60%.
