Abstract
1463161 Electro-photography COULTER INFORMATION SYSTEMS Inc 25 Jan 1974 [14 Sept 1973] 03622/74 Heading G2H Electro-photographic camera 10 comprises a photo-conductive member 12 and charging means 24 which charge the member simultaneously with exposure at such a rate that sensitization by charging replaces the use of a controlled duration of opening shutter. A photo-cell 84 measures incident light, and an electrometer 86 measures the charge applied, so that control 90 stops charging at a level appropriate to the light level. Liquid or powder developer is then applied to the photo-conductive member, and the developed image is fixed by heat
