(57) [Summary] [Purpose] To meet the demand for higher speed and higher resolution, Further, the present invention provides a toner for developing an electrostatic charge image, which is excellent in various properties such as moisture resistance, offset resistance, fixed image rubbing resistance, filming resistance, and charging stability. A binder resin component, and a carbon black graft polymer obtained by grafting onto a carbon black a polymer having a polysiloxane structure in at least a part thereof and having a reactive group for a surface functional group of carbon black. A toner for developing an electrostatic charge image, which comprises: |
