PURPOSE:To effectively prevent image flowing caused by corona generated substance which is generated by corona discharge and to maintain a good-quality image over a long term by providing a means for applying a substance which complements the lowering of the surface resistance of a photosensitive body to the surface of the photosensitive body. CONSTITUTION:The substance which complements the lowering of the surface resistance is applied to the surface of the photosensitive body 1. Namely, after solid paraffin whose electric resistance is >=10<14>OMEGAcm, whose dielectric constant is 1.5-4, and whose fusing point is >=55 deg.C is heated to a liquid state, an applying member is impregnated with the paraffin and wound to a core material singly to quintuply, so that an applying tool 12 is obtained. The cleaning member of a toner cleaning device 7 for removing the corona generated substance is principally composed of activated carbon fiber. Even when the corona generated substance is stuck to the surface layer of the photosensitive body 1, in such constitution, it is effectively removed by the cleaning member. Furthermore, when resistance becomes low because the surface layer of the photosensitive body 1 is damaged and the corona generated substance is stuck, the low resistance is complemented by applying the paraffin whose resistance is high and whose dielectric constant is low. |
