• G03G 13/01 for multicoloured copies
• G03G 13/02 Sensitising, i.e. laying-down a uniform charge
• G03G 13/04 Exposing, i.e. imagewise exposure by optically projecting the original image on a photoconductive recording material
• G03G 13/05 Imagewise charging, i.e. laying-down a charge in the configuration of an original image using a modulated stream of charged particles, e.g. of corona ions, modulated by a photoconductive control screen bearing a charge pattern or by optically activated charging means
• G03G 13/054 using X-rays, e.g. electroradiography
• G03G 13/056 using internal polarisation
• G03G 13/06 Developing
• G03G 13/14 Transferring a pattern to a second base
• G03G 13/2 Fixing, e.g. by using heat
• G03G 13/22 Processes involving the combination of more than one step according to groups
• G03G 13/26 for the production of printing plates for non-xerographic printing processes
• G03G 13/34 Editing, i.e. producing a composite image by copying one or more original images or parts thereof
