    摘要： A semiconductive polymer member is provided which comprises a semiconductive polymer composition, a polymer matrix and a conductive agent so that the member has an electric resistance ranging from 1 x 10 5 Ω ·cm to 1 x 10 10 Ω ·cm when measured under conditions of a temperature of from 15 to 32.5°C, a relative humidity of from 10 to 85% and a measuring potential of from 10 to 5000 V and has a positional variation in the electric resistance of not larger than ±20%. In addition, the electric resistance determined under conditions of a temperature of 15°C and a relative humidity of 10% is not larger than 50 times an electric resistance determined under conditions of a temperature of 32.5°C and a relative humidity of 85%. When the semiconductive polymer member is in the form of a roller, such a roller is suitable for use in electrophotography especially when it is employed in combination with a power supply for transfer devices, or a constant current or voltage power supply.

    摘要： An object, typically photoconductor drum (2) is electrically charged by placing a contact charger member (1) in abutment with the object to be charged (2) and applying voltage between the contact charger member (1) and the object (2). Charging is effected by properly controlling the capacitance of the contact charger member (1), the capacitance of the object (2), and the applied voltage. A sufficient charged potential is achieved through the application of a relatively low voltage, while preventing ozone generation. The portion of the charger member (1) which is in abutment with the object to be charged (2) has a less or greater work function than the surface of the object and can be made by a conductive polymer or a polyurethane having a resistivity of 10⁴ to 10¹² Ω.cm.
