摘要： A liquid type developing apparatus includes a developing liquid chamber containing a developing liquid comprised of toner and an organic solution. A recording sheet having an electrostatic latent image on its surface passes between a pair of upper and lower electrically conductive electrode members arranged so that at least one of such members contacts the developing liquid. An electric power source is connected to one of the electrode members for impressing a bias voltage thereto, such one member being arranged in non-contacting relationship with the chamber, and the other of such members being arranged in electrically conductive relationship with the tank, whereby any leakage of the impressed voltage due to attraction of the toner to the members, the tank or to bearings provided for the members, is substantially avoided.

摘要： A photoreceptor charge control arrangement to be employed for electrophotographic copying apparatuses wherein a specific circumferential portion on a uniformly charged photoreceptor is first exposed by a referenced exposure source to a specific amount of exposure and successively, the surface potential of the circumferential portion mentioned above is detected either at the relative position immediately before a position for an imagewise light exposing station or at the position juxtaposing the position of the station mentioned above, so that the successive comparison of the surface potential thus detected with a fixed reference is capable of effectively providing an appropriate control signal which can be employed to compensate the amount of exposure of the exposure source, irrespective of the surface condition of the photoreceptor.

摘要： A dielectric layer of copy paper is brought into contact with an electrostatic latent image bearing surface of a photosensitive plate by a first roller having an electric resistance value substantially higher than the rear face resistance value of the copy paper, the photosensitive plate having on its front face a dielectric layer for forming the latent image thereon and driven by a grounded roller. An electrically conductive lining element of the copy paper is substantially grounded by an electrically conductive second roller to transfer the electrostatic latent image by air breakdown discharge under the influence of the first and second rollers. The gap between the photosensitive plate and the copy paper has a width for air breakdown discharge according to Paschen's law.
