Polymer particles, method of producing the same, and toner for use in electrophotography comprising the polymer particles |
| 摘要 |
Polymer particles which are substantially spherical and have protrusions on the surface thereof, with such a particle size distribution that the volume mean diameter dv thereof is 1</=dv</=15 ( mu m), and the ratio of the volume mean diameter dv to the number mean diameter dn thereof, that is, dv/dn, is 1</=dv/dn</=1.2, are prepared, and used as a component for a toner for use in electrophotography.
