Abstract
A method and apparatus for xerographically printing a composite record based on first and second complementary sources of information. The first source of information is imaged onto a photoconductive medium having the property of persistent conductivity to form a conductive image representative thereof. The conductive image is then transferred onto a second photoconductive medium in the form of a latent electrostatic image. The second, complementary source of information is imaged onto the second photoconductive medium, preferably by a scanning laser, as an overlay on the image of the first source. The composite electrostatic image so formed is then developed by the application of toner material and transferred onto a record medium.
