TONER, DEVELOPING DEVICE, AND PROCESS CARTRIDGE |
| 摘要 |
A toner is provided. The toner includes toner particles each including a binder resin and a release agent. From 20% to 80% by number of the toner particles satisfy the following formulae (1) and (2):;⅔≦T/Dv≦1.5 (1);⅓≦R/Dv≦1.0 (2);wherein Dv represents a volume average particle diameter of the toner particles; and T and R represent the longest cross-sectional diameters of each toner particle and the release agent contained therein, respectively, measured by observing cross-sections of the toner particles with scanning transmission electron microscope. |

1. A toner, comprising:
toner particles, each including:
a binder resin; anda release agent, wherein from 20% to 80% by number of the toner particles satisfy the following formulae (1) and (2):
⅔≦T/Dv≦1.5 (1)⅓≦R/Rv≦1.0 (2)wherein Dv represents a volume average particle diameter of the toner particles; and T and R represent the longest cross-sectional diameters of each toner particle and the release agent contained therein, respectively, measured by observing cross-sections of the toner particles with scanning transmission electron microscope. |
