PURPOSE: To prevent the color mixture in a developing means, and to surely prevent the color mixture of a visualized image, by preliminarily providing a means bringing the developing means for every color into a non-developing state at the time capable of image forming. CONSTITUTION: An latent image for every color image formed on a photoreceptor is developed by exposure by exposing means. This device is provided with several developing device for every color arranged in parallel to the photoreceptor, and a control part 49 as development switching means capable of switching the developing device for each color to the developable state and the non-developing state. Then, at the time of the developable state, the developing device for every color is preliminarily made to be in a non- developing state. Thereby, in the developing device for visualizing the electrostatic latent image on the photoreceptor, toner of another color stuck on the photoreceptor is prevented from being mixed with the inside toner and causing the color mixture, therefore the color mixture of the visual image can be surely prevented. |
