PURPOSE:To form a green toner having an electrostatic charge characteristic of positive polarity and to permit easy change of a color toner to the green toner by using a chlorophyll as a coloring agent. CONSTITUTION:The green toner having the electrostatic charge characteristic of the positive polarity can be formed by using the chlorophyll as the coloring agent. In addition, the green toner which does not require the change of other toner compounding agents, etc. when the coloring agent is changed in order to change a color toner to the green toner can be formed. The chlorophyll has an elegant green color tone and is safe as the chlorophyll is a natural dye. The chlorophyll includes oil soluble and water soluble chlorophylls. The oil soluble chlorophyll is more preferable for use as the toner. There are also the chlorophylls bound with copper, iron, silver, cobalt, nickel, etc., in place of the magnesium contained in the natural chlorophyll. The copper chlorophyll bound with copper is more preferable from the relation with stability and color tone. |
