TONER FOR ELECTROPHOTOGRAPHY, IMAGE FORMING METHOD, AND PROCESS CARTRIDGE |
| 摘要 |
A toner for electrophotography, which contains a binder resin, and a release agent, wherein a maximum value of loss tangent of the toner at 95° C. to 115° C. is 8 or greater, as a viscoelasticity of the toner is measured, where the loss tangent is represented by the following formula: Loss tangent (tan δ)=loss elastic modulus (G″)/storage elastic modulus (G′). |

1. A toner for electrophotography, comprising:
a binder resin; and a release agent, wherein a maximum value of loss tangent of the toner at 95° C. to 115° C. is 8 or greater, as a viscoelasticity of the toner is measured, where the loss tangent is represented by the following formula:
Loss tangent(tan δ)=loss elastic modulus(G″)/storage elastic modulus(G′). |
