PCT No. PCT/DE97/00510 Sec. 371 Date Nov. 24, 1998 Sec. 102(e) Date Nov. 24, 1998 PCT Filed Mar. 13, 1997 PCT Pub. No. WO97/37286 PCT Pub. Date Oct. 9, 1997In an electrophotographic printing process as well as an electrophotographic printer for printing a substrate, a photo-sensitive layered system is brought to a homogeneous initial state by impressing an electrical field having a first direction. The photoconductive layer is exposed with predetermined image structures according to the image. The entire photoconductive layer is exposed uniformly through the cover layer and/or the electrode layer. Charged toner particles are applied to the cover layer in a development step. The toner image is then transferred to the substrate. If more than one copy is required, the development step and the transfer step are carried out a number of times, the electrical charge image present inside the layered system being retained. The substrate is conveyed at a very high speed by a conveyor device in this operational state.
