Abstract
PURPOSE: To let nearly even charging quantity distribution be exhibited and provide superior color characteristics by making combination use of the specific oil soluble dyes of good compatibility to a styrene base resin with this resin.
CONSTITUTION: A styrene base resin and oil soluble dyes of the type called solvent red 46 are melted and kneaded, after which the mixture is pulverized. If necessary, it is possible to add other coloring agents such as carbon black. The amount of using this dye is suitably about 1 to 30 wt% based on the resin in the case of electrophotography and about 1 to 40 wt% in the case of color electrophotography (magenta toner).
