Abstract

PURPOSE:To prevent pollution due to ozone by mainly installing an endless transferring belt composed of an insulating layer having >=10<10>OMEGA.cm specific resistance and an electrically conductive layer having <=10<8>OMEGA.cm specific resistance and a contact charger charging said insulating layer with electricity with polarity reverse to the polarity of toner particles. CONSTITUTION:Transferring belt 23 is composed of electrically conductive layer 23a having <=10<8>OMEGA.cm specific resistance, insulating layer 23b having >=10<10>OMEGA.cm specific resistance and superposed on the outside of layer 23a and adhesive layer 23c adhering layers 23a, 23b to each other. By rotating driving motor 26 of the transferring apparatus with the rotation of photoreceptor 4 and applying -1.5kV voltage to belt 23 from DC power source 49, belt 23 runs in synchronism with the rotation of photoreceptor 4, and it is charged with electricity with polarity reverse to the polarity of toner particles, that is, minus electricity. Using such a contact charger the generation of ozone is reduced to prevent the pollution of the air and the apparatus.
