摘要：
A method for preparing a functional particulate organic material, including providing a suspension of a particulate organic material having an acid group on a surface thereof; reacting a tri- or higher-valent metal cation with the acid group; and reacting at least one of an organic acid and an organic acid salt with the metal cation. A toner prepared by the method mentioned above. An image forming method including developing a latent image with the toner; transferring the toner image on a receiving material, optionally via an intermediate transfer medium, and fixing the toner image on the receiving material. A process cartridge including a developer container containing a developer including the toner mentioned above, and at least one of an image bearing member; a charger; a developing device; and a cleaner.
