PURPOSE:To prevent the degradation in the electrostatic chargeability of the parts right under an electrifier and corresponding to a discharge passage by mounting air filters having coating layers essentially consisting of an ozone removing agent on a base body contg. Al or iron or an alloy of Al or iron. CONSTITUTION:The air filters 17a, 17b having the coating layers essentially consisting of the ozone removing agent (e.g. active carbon, titanium oxide) are mounted onto the base body contg. Al or iron or the alloy of Al or iron of the electrophotographic device using a gaseous discharge method of a corona electrifier 8 as the electrifying means. As a result, the degradation in the electrostatic chargeability and image blur in the parts right under the electrifier and corresponding to the discharge passage are prevented and the high-quality images are obtd. |
