ABSTRACT:
The invention relates to an image forming device and method therefor solving the subject matter that, if the linear speed of the developing solution carrier for that of the latent image carrier is lowered in order to secure the development capacity, the line image is deteriorated and there occurs a troublesome matter such as the blanking at the halftone rear edge. Such image forming device of the present invention is provided with a two-component magnetic brush type developing apparatus in which the developing bias composed of the DC bias and the AC bias superposed thereon is applied to the developing apparatus, and the latent image formed on the latent image carrier is developed with the two-component developing solution including the magnetic toner and the magnetic carrier. In the image forming device, the magnetic substance including percentage of the magnetic toner is set to 5 wt %.about.35 wt %.
