To provide a developing method by which the developing ability of a developing device is enhanced and the occurrence of surface staining due to reversely electrified toner is suppressed, even when surface potential is changed within the range of 0 to 200 V, and to provide a device therefor, an image forming device and an image processing apparatus.
In the developing method and the developing device, latent image on a photoreceptor 1 is developed by carrying developer 12 on the surface of a developing sleeve 421, to which developing bias voltage is applied and feeding it to a developing area, and the dynamic resistance of the magnetic particles 11 of the developer is ≤102 to 106 Ω, half-value width in the profile of the particle size number distribution of toner in the developer carried on the developing sleeve is ≤28% of the particle size value of a peak in the profile of the particle size number distribution of the toner under the condition of the absolute value of the average electrified amount of the toner in the developer on the developing sleeve being ≤10 to 25 [μC/g].
