ABSTRACT:
An arrangement for removing charges trapped in the photoconductive material of an electrostatic copier. The arrangement includes a light-emitting unit for supplying the photoconductive material with light having a long wavelength to render the photoconductive layer non-conducting. Energy supplied in this long wavelength causes electric charges trapped in the photoconductive layer to be released in the presence of an electric field generated between the photoconductive layer and its conductive support member.
