Abstract
PURPOSE: To eliminate the effect of a preceding image and to form a good image free of a ghost image on a repeatedly used photoreceptor, by irradiating the photoreceptor having an insulating layer on its surface by a specified light after image formation and prior to using for re-forming an image.
CONSTITUTION: The surface of photosensitive drum 1 provided with a conductive layer, a photoconductive layer, and an insulating layer is charged uniformly with primary charger 2, and then, undergoes imagewise exposure of an original on original platen 12 from the backside of AC corona discharger 3 actuated at the same time. The whole surface of drum 1 is exposed with whole surface exposing lamp 4 to form a static latent image. This image is then developed with liquid developing apparatus 6. The surface of drum 1 is cleared of an excess of the liquid undergoes post-charging. The developed image is then transferred to a transfer medium. The surface of drum 1 is cleaned with blade cleaner 11, and subsequently exposed in an illuminance of above 2000 luxes, preferably above 5000 luxes 0.2 second before AC charging start with light source 25 for erasing a ghost image, and thus the second copying step starts.
