Negatively chargeable spherical toner, color image forming apparatus, and process for producing negatively chargeable spherical toner |
| abstract |
The present invention provides a negatively chargeable spherical toner having: a toner mother particle having a binder resin and a colorant, which has: a number average particle size of from 4.5 to 9 μm; a particle size distribution that has an integrated value of particle sizes of 3 μm or less of 1% or less; and an average sphericity of from 0.95 to 0.99; and an alumina fine particle externally added to the toner mother particle, which has a number average particle size of from 0.1 to 1.0 μm, wherein a work function (Φ t ) of the toner mother particle is larger than a work function (Φ A ) of the alumina fine particle by at least 0.4 eV. |
