发明名称 ELECTROSTATIC CHARGING DEVICE AND ELECTROPHOTOGRAPHIC DEVICE
摘要 PROBLEM TO BE SOLVED: To provide an electrostatic charging device and electrophotographic device, with which it is possible to make injection charging despite varying environment, with less change in the charging characteristics, and in good performance. SOLUTION: The arrangement according to the present invention includes an electrophotographic sensitive material, which has a photo-sensitive layer on a conductive support, and magnetic particles, and a charging member of this electrostatic charging device is installed in contact with the electrophotographic sensitive material and charges it when a voltage is impressed. That layer of the sensitive material which is the most apart from the conductive support has a volume resistivity of 10<8> -10<15>Ω.cm, and the magnetic particles have such a moisture absorbing characteristic that the ratio H/L lies between 1 and 4, where H and L are the maximum and minimum, respectively, of the water content of the particles. Besides the electrophotographic sensitive material and charging member, this electrophotographic device includes a photo-exposing means, developing means, and transcribing means.
