摘要： An image forming technique employing a screen photosensitive medium having therein a plurality of fine openings. Using such screen photosensitive medium an electrostatic latent image is formed on an electric charge retainable member to be modulated under the action of a modulated corona ion stream. A non-image area can be formed on the member to be modulated by providing an ion stream blocking member between a modulation ion source and the screen photosensitive medium to block the ion stream flowing from the ion source to the screen photosensitive medium at a desired and limited area. The present invention enables to form a very sharp boundary between image area and non-image area.
