    摘要： The present invention relates to a toner for electrophotography, and an object of the present invention is to improve various characteristics of the toner for electrophotography. A charge controlling agent composition obtained either by adding carbon therein during the preparation of the charge controlling agent or by mixing the charge controlling agent with carbon in the presence of a solvent, and an electro-photographic toner containing said composition are provided. The charge controlling agent composition wherein the charge controlling agent and carbon are uniformly dispersed, has excellent dispersibility in the resin, is freed from the problems of charging unstableness and scattering, and can provide an electro-photographic toner which provides a clear copied image.
