摘要： An electrophotographic method according to the present invention forms a color image on a photosensitive drum by repeating a cycle of charging, exposure and development for a plurality of times. The electrophotographic method comprises a step of applying a corona discharge component superposed with an AC voltage shifted to the negative or positive polarity which corresponds to that of the photosensitive drum to the photosensitive drum prior to the second image exposure so as to recharge the photosensitive drum.

摘要： A developing apparatus is provided with a developing roller for carrying a toner thereon and an elastic blade pressed against the surface of the developing roller to apply the toner thereto. The toner is thus applied to the surface of the developing roller by the elastic blade to form a thin layer of the toner on the surface of the developing roller. The thin layer is opposed to a photosensitive drum at a predetermined space to deposit the toner on an electrostatic latent image on the photosensitive drum. Magnets and magnetic particles are provided to prevent the toner from leaking out.

摘要： A developing apparatus is so set as to face the developed section of the electrostatic latent image-forming plane of the photosensitive drum, and causes a magnetic developing agent to be magnetically conducted to the electrostatic latent image-forming plane. Further, a magnet roll is so provided as to face that portion of the electrostatic latent image-forming plane of the photosensitive drum which has passed the developed region, thereby adsorptively removing the unnecessary particles of the developing agent which are deposited on the electrostatic latent image-forming plane. Therefore, the developing apparatus, though possessed of a relatively simple arrangement, has the advantages of suppressing the occurrence of the aforesaid tailing phenomenon, and enabling a distinct impression to be transcribed on a copy sheet with the reproducibility of fine lines prominently improved.

摘要： An arrangement for removing charges trapped in the photoconductive material of an electrostatic copier. The arrangement includes a light-emitting unit for supplying the photoconductive material with light having a long wavelength to render the photoconductive layer non-conducting. Energy supplied in this long wavelength causes electric charges trapped in the photoconductive layer to be released in the presence of an electric field generated between the photoconductive layer and its conductive support member.

摘要： The recording head have a substrate and a plurality of ring-shaped recording electrodes juxtaposed on the substrate. A counter electrode is located above the recording electrodes and spaced apart therefrom by a predetermined distance. Each recording electrode consists of a ring and a lead. A pulse generator is connected by an IC (not shown) to the leads, for applying a drive voltage to each recording electrode. The drive voltage consists of a bias voltage and a recording voltage higher than the bias voltage. When a bias voltage, having the same polarity as a charged polarity of coloring particles dispersed in an insulating liquid, is applied to each recording electrode, potential wells are formed. The coloring particles in ink are thereby trapped in the ring of the electrodes. The coloring particles agglomerate in the apical part of the ink meniscus formed at the recording electrode. When the recording voltage, having the same polarity as a charged polarity of the coloring particles. is applied to any recording electrodes selected in accordance with an image signal, the agglomeration of coloring particles flies from the potential well toward the counter electrode, forming any dot on a recording medium interposed between the recording head and the counter electrode.

摘要： A developing device comprises a toner separating member placed in contact with a developing roller for developing a latent image on a photoconductive drum into a visible image with nonmagnetic toner conveyed as a one-component developing agent, and a toner feeding roller provided near the toner separating member. The toner separating member allows the toner which has passed on a developing position of the photosensitive drum to be separated from the developing roller. The toner feeding roller allows the separated toner to be transferred toward a toner receiving side of the developing roller.
