| abstract |
The invention relates to (1) a toner with inorganic fine particles added externally, the inorganic fine particles having a specified mean particle size and a specified particle size distribution, and (2) a toner having specified particle size, specific gravity, and angle of toner repose, and a developing agent comprising the toner and a carrier. The toner of the present invention has good environmental stability, non-sticking characteristic, and good storage stability under hot conditions, and is capable of forming good images without aggregation noise. Further, the toner is not liable to produce toner dust and does not damage the photoconductor. The toner is particularly suitable for full-color image formation. |
