Abstract

1327486 Electro-photography RANK XEROX Ltd 24 Nov 1970 [1 Dec 1969] 55854/70 Heading G2H In a superimposed multi-colour electrophotographic process in which the steps of uniform charging and imagewise exposure are applied to photo-conductive material already bearing a toner image, a uniform charge of the desired polarity, producing a differential polarity in the toner image areas is first applied, whereafter a uniform charge of the opposite polarity is applied, before or after exposure, to remove the differential polarity.
