ABSTRACT:
A toner including toner particles including a binder resin, and a modified layered inorganic material in which at least part of interlayer ions is replaced with an organic ion, and a fatty acid metal compound located on a surface of the toner particles; and an external additive located on the fatty acid metal compound, wherein the external additive is a material different from the fatty acid metal compound. An image forming apparatus including an image bearing member; a developing device configured to develop the electrostatic latent image with a developer including the toner; a transfer device; and a fixing device. A method for preparing the toner including dispersing or emulsifying a toner composition including a modified layered inorganic material to prepare toner particles; mixing a fatty acid metal compound with the toner particles; and second mixing the toner particles with an external additive.
