Abstract
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.ltoreq.dv.ltoreq.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.ltoreq.dv/dn.ltoreq.1.2, are prepared, and used as a component for a toner for use in electrophotography.
