Abstract
A method of obtaining a number of copies transferred from one electrostatic latent image produced on an electric charge carrying member coated on an electrically conductive transfer body is disclosed. The method comprises the successive steps of producing an electrostatic latent image charge on the transfer body, developing the electrostatic latent image charge into a toned picture image, applying a bias voltage between an electrically conductive screen arranged near a transfer receiving medium made in contact with the transfer body on the one hand and the transfer body on the other hand and at the same time charging the transfer receiving medium through the electrically conductive screen with a corona source of ions. The method can transfer the electrostatic latent image produced on the transfer body to the transfer receiving medium without damaging the electrostatic latent image at a high speed with a high efficiency.
