Abstract
In the method and apparatus of the present invention, a voltage of up to 1,800 V is applied to the photoconductor surface of the drum of an electrophotographic copier. A latent charge image is formed by exposing the photoconductor surface and the latent charge image is developed by contact with a developing liquid to form a toner image. Excess developer is removed by a stripping roller which contacts the drum and rotates at a speed which is up to 20% faster than that of the drum.
