- G03G 15/23 specially adapted for copying both sides of an original or for copying on both sides of a recording or image-receiving material
- G03G 15/24 whereby at least two steps are performed simultaneously
- G03G 15/26 in which the charge pattern is obtained by projection of the entire image, i.e. whole-frame projection (G03G15/04 takes precedence)
- G03G 15/28 in which projection is obtained by line scanning (G03G15/04 takes precedence)
- G03G 15/32 in which the charge pattern is formed dotwise, (G03G15/04, G03G15/05, G03G15/34 take precedence)
- G03G 15/34 in which the powder image is formed directly on the recording material
