CONTINUOUS HIGH-SPEED COPYING METHOD OF MULTIPLE NUMBER OF COPIES

摘要

PURPOSE:To permit stable copying at a high speed with extremely little generation of oscillation and to improve the efficiency of the rear operation of a copying machine by constituting said machine in such a manner that all the original images are once transferred to an insulating film drum and thereafter the necessary number of sheets are copied by rotation of the insulating film drum or photosensitive drum in the case of copying continuously multiple sheets. CONSTITUTION:A latent image is formed on the photosensitive drum 5 and is developed to a sensible image by sticking a toner thereto in a developing tank 13. The image is transferred onto the insulating film drum 6. Such process is repeated plural times. The number of the repetition is below the max. number of the original sheets which can be formed on the drum 6. The drum 6 is detached from the drum 5 and the plural original images transferred onto the drum 6 are successively exposed to the drum 5 to form the 2nd latent images. The 2nd latent images are developed to sensible images by the tank 13. These images are transferred to the transfer paper 21 fed from the right by a transfer device 11 and the paper is further fed to the left and is fixed by a heat roller 18.
