PROBLEM TO BE SOLVED: To provide an electrostatic image developing method capable of obtaining a sharp image, improving low-temperature fixability and offset resistance, and having stable charging performance without fog even in long-term durability. It is intended to provide a toner. The present invention relates to a toner for developing an electrostatic image formed of a composition containing at least a polymer component, a colorant, a wax and a charge control agent, wherein the polymer component of the composition is (a) ) Substantially free of THF insolubles, (B) The THF-soluble component of the polymer component has a main peak and a sub-peak or a shoulder in a specific region in a GPC chromatogram, and (c) the acid value (A VL ) of the low molecular weight polymer has a high molecular weight. Greater than the acid value (A VH ) of the polymer, the wax has an acid value, and the acid value (A VWax ) is A VL And a toner for developing an electrostatic charge image. |
