PURPOSE:To obtain a photoconductive toner superior in spectral sensitivity, sharply sensitive to red light and to form a magenta image freed of color mackling in a short time by using a toner having photosensitivity in the visible light region of specified wavelengths and coloring it to magenta. CONSTITUTION:The present toner has photosensitivity to the visible light region of >=600nm wavelengths, and is colored to magenta, preferably, such as hues belonging to the hue designation range of 1.0RP-5.0R of the Munsell System. it is preferable for the toner to have sharp sensitivity to >=600nm wavelengths as sensitivity characteristics, and the sensitivity max. point at 610-650nm wavelengths, and occupy >=80% of the total sensitivity in the total visible region at 600-700nm wavelengths. Since such a toner has selective sensitivity to only a red light, and it is colored to magenta, the use of this photoconductive toner permits a color image freed of color mackling to be formed in a short time from color image signals by executing an electrophotographic operation in only one time. |
