ELECTROPHOTOGRAPHIC TONER |
| 摘要 |
An electrophotographic toner includes capsule toner particles that each include an anionic toner core having a zeta potential at pH 4 of no greater than −5 mV and a cationic shell layer disposed over a surface of the toner core. Each of the capsule toner particles has, at a surface thereof, a sodium concentration of no less than 200 ppm and no greater than 1,000 ppm as measured by an ICP spectrometer. |

1. An electrophotographic toner comprising capsule toner particles each including:
an anionic toner core having a zeta potential at pH 4 of no greater than −5 mV; and a cationic shell layer disposed over a surface of the toner core, wherein each of the capsule toner particles has, at a surface thereof, a sodium concentration of no less than 200 ppm and no greater than 1,000 ppm as measured by an inductively coupled plasma spectrometer. |
