Abstract: 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.

Abstract: A sheet original feeding apparatus comprises a sheet original stacking tray on which sheet originals to be treated are stacked as an original stack. A sheet original separator separates and supplies the sheet original one by one from the bottom of the original stack stacked on the sheet original stacking tray. A sheet original feeding path is provided for directing the sheet original separated by the sheet original separator. A sheet original feeder feeds in a forward direction the sheet original directed by the original feeding path to an image reading portion. The sheet original feeding means is also operable in a reverse direction, and the sheet original feeding path is arranged at one side of the sheet original feeder. A first sheet original ejecting path is further provided for returning the sheet original fed in the reverse direction by the sheet original feeder to the sheet original stacking tray from a same side of the sheet original feeder as the sheet original feeding path. A second sheet original ejecting path returns the sheet original fed in the forward direction by the sheet original feeder to the sheet original stacking tray. The second sheet original ejection path is arranged at a side opposite to the sheet original feeder means as the sheet original feeding path.
