ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER, ELECTROSTATIC CHARGE IMAGE DEVELOPER, AND TONER CARTRIDGE |
| 摘要 |
An electrostatic charge image developing toner includes toner particles including a binder resin and a metallic pigment and silica particles having an equivalent circle diameter E of greater than 0.10 μm, wherein a relationship between a number-average maximum thickness C and a number-average equivalent circle diameter D of the toner particles satisfies 0.700<C/D<1.220, a number-average equivalent circle diameter d of the silica particles satisfies 0.10 μm<d<0.30 μm, and the content of silica particles, having a ratio F/G of a circumferential length F to a circumference G calculated from the equivalent circle diameter E of 1.10 to 3.00, with respect to the total number of silica particles is 30% by number to 100% by number. |

1. An electrostatic charge image developing toner comprising:
toner particles including a binder resin and a metallic pigment, and silica particles having an equivalent circle diameter E of greater than 0.10 μm, wherein a relationship between a number-average maximum thickness C and a number-average equivalent circle diameter D of the toner particles satisfies 0.700<C/D<1.220, a number-average equivalent circle diameter d of the silica particles satisfies 0.10 μm<d<0.30 μm, and the content of silica particles having a ratio F/G of a circumferential length F to a circumference G calculated from the equivalent circle diameter E of 1 . 10 to 3.00 is 30% by number to 100% by number with respect to the total number of silica particles. |
