Abstract

PURPOSE: To make it possible to form a multicolor image with good quality easily and rapidly, by forming a visible image based on the first latent image on the latent image supporter such as a photosensitive drum, etc., subsequently forming the second latent image and executing nonchafing developing treatment with the second color developing agent.
CONSTITUTION: After a latent image of black image part of the original has been formed on the photosensitive drum 1 by exposure through a red filter 9, etc. by the first rotation of the drum 1, it is subject to developing treatment by the developing unit 17 such as cascade system, etc. A latent image of the red image part of the original formed on the charged particle flow control screen 13 which is moved linearly by synchronizing with the rotary movement of the drum 1 is transferred on the drum 1 at the time of the second rotation of the drum 1. And the nonchafing developing treatment by a red developing agent is performed by the device 17, and it does not exert influence on the existing black visible image. The visible image is transferred at the time of the third rotation of the drum 1, and a multicolor image of good quality without image distortion is formed easily and rapidly by means of a few processes. In this regard, the same result as the foregoing is obtained even in case of the nonchafing developing treatment method such as impression system or powder-craft system.
