CHARGING DEVICE, IMAGE FORMING APPARATUS AND CHARGING METHOD

摘要

An electrification device, an image forming device and an electrification method are provided to inhibit the generation of ozone, and to improve the efficiency of electrification. An elastic member(101) is contacted with an objective electrification body. A voltage applying device applies the specific bias voltage to the electrification body through the elastic member so that the objective electrification body is electrified. The elastic member is contacted with the objective electrification body and made of materials including diamond particles. The average diameter of diamond particles is 3 nanometer to 30 micrometer. The elastic member is a rotatably supported roller type elastic member. A driving unit drives the elastic member and a portion of the elastic member contacted with the objective electrification body is moved relatively.
