Title:
MULTIIMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JPH01133085
Kind Code:
A
Abstract:
PURPOSE:To form multiimage by changing the gradation characteristics of respective images so that the adequate images are obtd. with all mingled originals by operating a latent image forming means and developing means according to the number of the kinds of the gradation characteristics. CONSTITUTION:This device has the latent image forming means 2 which forms the electrostatic latent image on a photosensitive body 1 by projecting the image light from the original onto the photosensitive body 1, the developing means 5, 6 which develop the latent image, and control means which operates the latent image forming means 2 and the developing means 5, 6 for each of the gradations to the different gradation regions of the original. The control means forms the synthesized image by operating the latent image forming means 2 and the developing means 5, 6 by as much as the number of kinds of gradation characteristics existing in one original. The high-quality images meeting the respective characteristics are thus obtd. at a high speed by executing the development operations by as much as the number of the kinds of the gradation characteristics on the original.
