An electrophotographic toner containing a specific compound as the charge control agent is described. The electrophotographic toner according to the present invention have a sharper distribution of charge and better moisture resistance and charge durability than those of a toner wherein a conventional charge control agent is used. Therefore it can provide an image having a very high gradation and has a very high capability of repeatedly forming an image. Since the charge control agent, as such, is essentially colorless, a colorant can freely be selected according to a hue required of a color toner and the toner is not detrimental to the hue inherent in a dye and a pigment. The charge control agent is highly safe to environment.
