Abstract

A screened photoconductive member can be employed to generate both positive and negative copies. The photoconductive member is formed with an optical screen pattern on the free surface thereof. The optical screen pattern comprises a light absorbing material which is electrically inert during the charging ar?d imaging of the photoconductive member. To obtain a negative reproduction of an original document, the photoconductive member is charged and imagewise exposed. Alternatively, in order to obtain a positive reproduction of an original document, the photoconductive member is charged and exposed uniformly. Thereafter, the photoconductive member is imagewise exposed. In both cases, latent images are formed which are subsequently developed and transferred to a copy sheet. Thereafter, the resultant powder images on the copy sheet are permanently affixed thereto.
