    摘要: There are disclosed metallic soap fine particles which have an average particle size of 4 .mu.m or smaller and have a content of particles having particle sizes of 10 .mu.m or larger of at most 4% by weight based on the whole metallic soap fine particles; a process for producing the metallic soap fine particles, comprising mixing (a) an aqueous solution containing 0.001 to 20% by weight of an alkali metal salt or an ammonium salt of a fatty acid having 4 to 30 carbon atoms with (b) an aqueous solution or dispersion containing 0.001 to 20% by weight of an inorganic metal salt at a specific temperature to form a slurry of the metallic soap, and drying the resultant slurry at a specific temperature. The metallic soap, which has remarkably fine particles and narrow particle size distribution, is well suited for use e.g. as a toner additive in an electrophotographic copying machine by virtue of the improvements in blocking resistance, fluidity and eliminability of the toner, and also as a cleaning aid in the same owing to the improvement in cleaning performance for residual toner without impairing the surface of a picture image support.
