Organosilicone fine particles of size in the range of 0.1 - 20µm, each having 20 or more faces with indefinite shapes and a network of convex parts that surround these faces with indefinite shapes on its surface, and being spherical as a whole respond to highly advanced requirements of recent years including improvements in optical characteristics of resin compounds, usability and feeling of cosmetics and maintainability of fluidity of development toners. The invention further provides methods of producing such organosilicone fine particles.
