摘要：
There is provided by the present invention an electrifying roller having a roller layer having at least two layers of an elastic layer provided on a peripheral surface of core metal and a surface layer covering the elastic layer, wherein a slope (.DELTA.I/.DELTA.V) of the V-I characteristics of the roller layer is 1 or less, the electrifying roller is rotated in contact with the light-sensing drum, a voltage is loaded from a power supply unit to the core metal of the electrifying roller, and a surface of the light-sensing drum is electrified to a surface potential (Vs).
