ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER, MANUFACTURING METHOD THEREOF, ELECTROSTATIC CHARGE IMAGE DEVELOPER, AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner which has excellent electrostatic charging property and prevents a colorant from being exposed on a toner surface. SOLUTION: The electrostatic charge image developing toner includes a binder resin composed of a polyester resin, a core layer including a release agent composed of polyester wax and a colorant, and a shell layer coating the surface of the core layer, in which volume average grain size is 3 to 8μm and the ratio of the colorant existing in the region within 200 nm from the extreme surface of the toner is≤10%.
