Black toner |
abstract |
To provide a black toner having excellent charging property and transferring property against a severe environmental change. The black toner includes toner particle containing at least a binder resin, carbon black and a releasing agent, wherein: the toner particles have a weight-average particle diameter of 3.5 to 8.0 mu m; total amount of acid value and hydroxyl value of the toner is 30 to 75 mgKOH/g; average circularity of particles contained in the toner having circle-equivalent diameter of 2 mu m or more is 0.915 to 0.960; loss tangent tan delta (10<3> to 10<4> Hz) of the toner is represented by the following expression: <DF>tan delta (10<3> to 10<4> Hz) </= 0.0060 </DF> where the loss tangent tan delta is represented by epsilon "/ epsilon ' where epsilon " denotes dielectric loss factor and epsilon ' denotes dielectric constant, and tan delta (10<3> to 10<4> Hz) denotes the loss tangent in a frequency range of 10<3> to 10<4> Hz; and a ratio of tan delta (10<5> Hz) to tan delta (5 x 10<4> Hz) is represented by the following expression: <DF>1.05 </= tan delta (10<5> Hz) / tan delta (5 x 10<4> Hz) </= 1.40 </DF> where tan delta (10<5> Hz) denotes loss tangent at the frequency of 10<5> Hz and tan delta (5 x 10<4> Hz) denotes loss tangent at the frequency of 5 x 10<4> Hz. |
