ABSTRACT:
According to the present invention, the photosensitive member and the electrostatic information recording medium are immersed in the toner after image exposure is performed, and the electric field is formed in the gap by short-circuiting between the electrodes of the photosensitive member and the electrostatic information recording medium. Also, bias voltage is applied between the electrodes of the photosensitive member and the electrostatic information recording medium, and the surfaces of the electrostatic information recording medium and the photosensitive member are immersed in the toner. Bias voltage is set to higher than the potential on the unexposed portion and lower than the maximum potential of the exposed portion on the electrostatic information recording medium or the photosensitive member, and toner development of electrostatic latent image is performed with high fidelity on the photosensitive member to form positive or negative image.
