<P>PROBLEM TO BE SOLVED: To perform dust-free high-quality image formation which is sufficiently applicable to a cleaner-less process, and to perform dust-free high-quality image formation which ensures good transfer efficiency, prevents reverse transferring and color mixture resulting from the reverse transferring, and is sufficiently applicable to a cleaner-less process. <P>SOLUTION: The ratio of the toner particles having a particle diameter of not more than A×0.5 (μm) (wherein A is a 50% average particle diameter (μm)) and the ratio of the toner particles having a particle diameter of not less than A×1.5 (μm) (wherein A is a 50% average particle diameter (μm)) are both confined to not more than 5% by number in a number particle size distribution, the ratio of the toner particles having an adhesive strength of not more than 1.3×10<SP>-8</SP>(N) is confined to 10% by weight or less and the ratio of the toner particles having an adhesive strength of not less than 3×10<SP>-7</SP>(N) is confined to 5% by weight or less in a distribution of adhesive strength to the surface of the image carrier. <P>COPYRIGHT: (C)2007,JPO&INPIT |
