Title: Electrophotographic device
Inventor: SHINOHARA KATSUHIRO
IPC: G03G15/06
Filed: 1995-06-09
Abstract: PURPOSE: To realize a best printing quality by making the difference between photoreceptor potential and magnet roll voltage variable and freely adjustable. CONSTITUTION: This electrophotographic device is provided with an electrifier 2 connected to a high-voltage power source for electrifying 1, a magnet roll for developing 5 connected to a high-voltage power source for developing 9 and a printing density selecting mechanism 10 connected to the power sources 1 and 9. The output of the high-voltage power source for developing 9 applied to the magnet roll 5 is increased by the printing density selecting mechanism 10, to make a printing density high.  Since it is necessary that the difference between the potential of the photoreceptor 3 and the voltage of the magnet roll 5 is set in optimum conditions for reducing surface staining, a change in the output of the high-voltage power source for electrifying 1 is simultaneousry required.A potential difference changing mechanism 11 is connected to the power sources 1 and 9, so that the difference between the photoreceptor potential and the magnet roll voltage is made variable and its magnitude is adjusted. Thus, the proper difference between the photoreceptor potential and the magnet roll voltage can be selected.
