ABSTRACT:
A developing device for use in an image forming apparatus and having a developing roller, developing sleeve or similar developer carrier for supplying a one-component developer, or toner, to a latent image which is electrostatically formed on an image carrier such as a photoconductive element. A dielectric layer forming part of the developer carrier and closely related to the fluctuation of developing characteristic has a frequency characteristic which is confined in a predetermined range. Hence, the device is operable in a desirable manner by confining the fluctuation of developing characteristic ascribable to that of developing linear speed in a predetermined range without resorting to the actual measurement of a response characteristic of a developer carrier.
