| description | PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that has high fluidity, and can suppress fogging on a non-image part, density unevenness of a half-tone image, and an abnormal increase of toner consumption, which are caused by bleeding of a mold release agent to the surface of toner particles; and a manufacturing method of the toner for electrostatic charge image development.SOLUTION: There is provided a toner for electrostatic charge image development that includes toner base particles containing a binder resin, colorant, a mold release agent, and a charge adjusting agent. The mold release agent has the melting point of 73 to 76°C, and the penetration degree of 3 or less at 45°C; the circularity of the toner base particles is 0.910 or more as a 10% integrated value of the number frequency from the low circularity, and 0.975 to 0.985 as a 50% integrated value of the number frequency from the low circularity. Also provided is a manufacturing method of the toner for electrostatic charge image development. |
