Abstract

PURPOSE:To prevent picture contamination due to the first half fog and a memory effect, and lowering of a sensitivity after a pause by charging with exposure a photosensitive body having a photoconductive layer containing Cd and Se after repeating a process for sensitization over two times or more using an effect of its specific previous record. CONSTITUTION:In a copying machine equipped with a photosensitive drum 1 having a photoconductive layer containing Cd and Se, the machine is equipped with a cleaning device 11, an eraser 12, a sensitizing unit 13 (comprises a charger 14 for its previous record charging and an eraser 15 for its previous record exposure) and a corona charger 2 behind a charger 8 for transfer. Along with a start of the drum 1, at the charger 8 the first previous record sensitization is executed, the drum 1 is charged in the same polarity as one in electrostatic latent image formation and then at the sensitizing unit 13 the second previous record sensitization is executed. In certain circumstances, using the units 15 of two sets it may be further sensitized. Still more, normal charging 2 is performed, picture exposure 5 is done with development and is transferred on coping paper 7. Thus overlapping of pictures due to the first half fog and a memory effect is removed at a double uses in part of the drum 1. Further lowering of a sensitivity after long time stop is avoided.
