Abstract

PURPOSE: To obtain the toner which is strong in negative polarity, is charged evenly and provides superior color characteristic by using the specific pigments as coloring agents for magenta toner.
CONSTITUTION: Coloring agents of formula 1 thru 4 alone or two or more kinds may be combined but 1 to 10pts.wt. thereof are thermally kneaded for 100pts.wt. of resins in the magenta toner for electrophotography and after cooling the mixture is ground with a jet mill or the like, whereby the magenta toner of grain sizes 5 to 20μm is produced. To 3 parts of this toner is mixed 100 parts of iron powder carrier and the mixture is used as a developer, whereby the distinct images free from any change in developing characteristics of the toner at the running time are obtained.
