ELECTROPHOTOGRAPHIC REPRODUCING METHOD, WITH REVERSE DEVELOPMENT, ON A CONDUCTIVE CARRIER USING A SINGLE-MAGNETIC MAGNETIC DEVELOPMENT POWDER AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

The invention relates to an electrophygraphic reproduction method, with reverse development on a conducting support using a single-mode magnetic development powder in which: a charge image is produced on the basis of FIG. A PHOTOCONDUCTOR SURFACE 1; / P P -ON ACHIEVES A MAGNETIC DEVELOPMENT POWDER 3 MONOCOMPONENT IN THE SURROUNDING OF THE PHOTOCONDUCTIVE SURFACE BY MAGNETIC MEANS 2; / P P -ON DEVELOPED IN AN INVERSE MANNER, L CHARGE IMAGE FOR FORMING A POWDER IMAGE; ON POWDER IMAGE IS TRANSFERRED ON A CONDUCTIVE BRACKET 5 IN THE PRESENCE OF A 7 VOLATIL VOLATILE DIELECTRIC LIQUID LAYER OF VOLUME RESISTIVITY GREATER THAN 10OCMCM, SAID LIQUID REMAINING PRESENT ON THE CONDUCTIVE BRACKET 5 DURING AT LEAST THE TIME NECESSARY FOR THE TRANSFER OF THE POWDER IMAGE ON THIS CONDUCTIVE SUPPORT 5; / P P - POSSIBLY, THIS POWDER IMAGE IS TRANSFERRED FROM THE CONDUCTIVE SUPPORT 5 TO A SUPPORT OF COPY 9; / P P -ON FIXED THIS PICTURE OF POWDER TRA NSFEREE; / P P -ON CONNECTS THE PHOTOCONDUCTOR SURFACE 1, THE MAGNETIC MEANS 2 AND THE CONDUCTIVE SUPPORT 5 TO THE TERMINAL 23 OF THE SAME SIGNS THAT THAT OF THE CHARGE OF THE PHOTOCONDUCTIVE SURFACE 1 OF AT LEAST ONE GENERATOR OF VOLTAGE 13. / P P IT ALSO CONCERNS THE DEVICE FOR IMPLEMENTING THE METHOD. / P
