<p>PROBLEM TO BE SOLVED: To provide an electrostatic image developing toner which gives such an excellent developed image quality that does not change for a long time, and with which an excellent developed image is always formed in spite of environmental change ranging from a low temperature low humidity to a high temperature high humidity. SOLUTION: In the electrostatic image developing toner in which at least one kind or more of inorganic oxides are externally added to a toner particle consisting of a thermoplastic resin, a colorant, an electrostatic charge control agent and a releasing agent, the inorganic oxide is externally added under a condition in which product of linear velocityα(m/sec) and externally adding and blending time T (sec) satisfies a numerical formula: 3×10<2> <α×T/3<8×10<2> .</p> |
