摘要： An electrostatic recording apparatus is provided which comprises a recording electrode with a plurality of stylus electrodes and a developing device with a back electrode provided on opposite sides of a recording medium. The recording apparatus is capable of simultaneously processing the forming of and development of a latent image by using the recording electrode which has a magnetic piece embedded at a tip portion thereof. A magnetic field is concentrated in its path and is increased in a narrow gap region between the recording electrode and the back electrode. Toner chains of magnetic particles in the developing process can easily stand upright on the back electrode, and can thus easily and uniformly contact the recording medium. Dot defects on a formed image, are therefore, avoided. The present invention is directed to several embodiments of the magnetic piece and the manner of embedding the magnetic piece in the recording electrode.

摘要： A compact and simple structured electrophotographic printing apparatus having a single magnetic developer, in which an accumulation of toner particles is formed on a photosensitive member at a downstream position from the magnetic developer. The accumulation of the toner particles is formed by moving a photosensitive film and a magnetic brush in rubbing contact with the film in mutually opposite directions, or by deforming a magnetic field generated by the magnetic developer, using a magnetic piece. A recording electrode is disposed on a sleeve of the magnetic developer and facing the photosensitive film. Bias voltages, having polarities opposite to each other with respect to the photosensitive film, are respectively applied to the recording electrode and the sleeve. An optical beam is projected onto the photosensitive film in a region facing the recording electrode. Thus, with the aid of toner particles located between the recording electrode and the photosensitive film and the accumulation of the toner particles, sensitizing, developing and scavenging are carried out simultaneously, and thus a toner image is produced on the photosensitive film. For a magnetic developer having a rotatable sleeve, a specially designed recording electrode is disclosed. The photosensitve member may be in the form of a solid flat plane, a drum, or a flexible belt-like film.

摘要： An electrophotographic printing apparatus employs a laminated, photosensitive medium including transparent supporting and conducting layers and a photosensitive layer defining the top surface of the medium, on which a toner image is formed. A first developer, maintained at a voltage of the same polarity as the toner particles, forms a uniform layer of charged toner particles on the surface of the photoconductive layer, the charged particles adhering to the surface. Simultaneously or subsequently, an optical beam is projected onto the photoconductive layer in accordance with the image to be printed, rendering the selectively exposed portions sufficiently conductive to permit charges of opposite polarity to be injected into the photoconductive layer from the conducting layer; the photoconductive layer establishes trapping potential levels therein, permitting the charges to traverse the layer to positions adjacent the top surface thereof. Upon extinguishing the optical beam, the photoconductive layer reverts to a nonconductive state, fixing the trapped charges in position as a laten electrostatic image. The latent electrostatic image establishes a field, or Coulomb force, which closely adheres the oppositely charged toner particles to the surface. In a second developing step, a developer, to which is applied a voltage of opposite polarity relative to that of the toner particles, then removes the toner particles from the nonexposed portions of the surface; the toner particles on the exposed portions of the surface are more firmly adhered thereto by virtue of the latent electrostatic image and thus a substantial portion thereof remain, providing a high contrast toner particle image for subsequent transfer to a suitable recording medium.
