Abstract
PURPOSE:To make sharp images by providing latent image formation, development of the dry type toner, another latent image formation, and development of the dry toner, putting the developer of the 2nd development into the noncontact state with a photoreceptor and electro-mechanically giving disturbance to said developer. CONSTITUTION:The 1st latent image forming means for forming charge on a recorder, and a developing means for the dry toner of the 1st color are provided, and the developing means for the 2nd color is provided. The developer of this developing means is put in the noncontact state with a photoreceptor. The developing means of the 2nd color has a magnetic roll 6, a sleeve 7, and the 2nd color developer 8, and vias boltages Vb, Vc are applied by DC, AC power sources 9, 10 to the sleeve 7. The efect of firmly holding the toner on the photoreceptor is accomplished by the DC bias voltage Vb, and the AC bias voltage Vc is applied in the 100- 1,000V range to disturb the attraction forces among the developers, thereby making up the decrease in developing capacity.
