ABSTRACT:
In an electrophotographic process in which an electrostatic latent image formed on the surface of a photosensitive member according to conventional electrophotography is transferred onto a latent image receptor sheet and the transferred latent image converted into a visual image with a developer, the improvement that when the receptor sheet is brought into contact with the photosensitive member to transfer the latent image from it onto the sheet, a bias voltage containing a high frequency component is applied across the member and the sheet facilitating a positive and uniform transfer to improve the continuous tone quality of the resulting image.
