PROBLEM TO BE SOLVED: To provide an electrification member for DC charging capable of minimizing a toner soiling, suitable to simultaneous developing and cleaning system, and an image forming device provided with this electrification member, capable of stably transferring and forming the image with excellent image quality over a long period. SOLUTION: In this image forming device applying the reversal developing system/simultaneous developing and cleaning system, the charge for the image carrier by charging means 2, is performed by the electrification member arranged in contact with or close to the image carrier, on which DC voltage is applied, and the triboelectric charge polarity with regard to the toner on the surface opposite to the image carrier of the electrification member 2 is made opposite to the toner charge polarity. |
