PURPOSE:To form the required number of visible images without deterioration in quality, by forming plural visible images from the same latent image by process control, interrupting the formation of the visible images, and reforming the latent image again, then continuing the formation of the visible images. CONSTITUTION:The sequential control including the formation of the primary latent image on screen drum, the formation of the 2nd latent image wherein said image is retained on an insulation drum, and the formation of a visible image from the 2nd latent image, etc. is accomplished by the process control with a CPU 401. When the formation of the visible images by the same latent image on the insulation drum attains a prescribed number, the formation of the visible images is interrupted by the output of a coincidence circuit 416 upon coincidence of the set number of a memory 203 and the number of revolutions of the insulation drum as counted by counters 413, 414 and the latent image by the screen drum and the insulation drum is formed again, whereafter the formation of the visible images is continued. The repetition is accomplished by the number of times of setting according to the number of the formation of the visible images in the memory 202 of the screen drum. A required number of the visible images having good quality are formed from the latent image having no deterioration. |
