The method of producing a duplex copy by simultaneously placing images of the original subject matter to be reproduced on both sides of a sheet of final support material. A first latent electrostatic image and a second latent electrostatic image containing original input scene information are sequentially formed on a photoconductive plate and developed in the conventional xerographic manner by contacting the charged images with oppositely charged toner particles. The first image is transferred to an image storage member where the polarity of the charged toner particles making up the image is reversed. The first image, carried on the support member, is then brought adjacent to the second image on the photoreceptor surface and a sheet of final support material interposed therebetween. The two oppositely charged images are subjected to an electrostatic force of a polarity and a potential to produce simultaneously a transfer of the images to opposite sides of the final support sheet.
