摘要:
An electrostatic charge image developing toner includes toner particles containing a binder resin and pigment particles and an external additive containing fluorine resin particles, wherein the electrostatic charge image developing toner satisfies the following expression: 2≦A/B≦100, wherein A represents reflectance at an acceptance angle of +30° which is measured when a solid image is formed using the electrostatic charge image developing toner and the solid image is irradiated with incident light at an incidence angle of −45° by the use of a variable-angle photometer, and B represents reflectance at an acceptance angle of −30° which is measured when the solid image is irradiated with incident light at an incidence angle of −45° by the use of the variable-angle photometer.
