ABSTRACT:
An electrostatic charge is applied to a charge carrier and the latter is thereupon contacted with one side of a sheet-material copy carrier. Thereafter, an original is imaged onto the charge carrier to produce thereon a latent electrostatic image field which penetrates the copy carrier, whereupon the latent image is developed on the copy carrier by contacting the other side thereof with developer material.
