Liquid developing method and apparatus for electrophotography, and electrodes therefor

摘要

A liquid electrophotographic development method where electrodes are arranged only on the side of the photosensitive layer of a master, developing liquid is supplied between the master and the electrodes, and conductors are made to come into contact with the base of the master so that an electric field is generated between the photosensitive plane and the electrodes for development. The electrode to be used for the electrophotographic development method includes conductive wires of a plural number which are arranged in the direction perpendicular to the traveling direction of the material so as to come into contact with the conductive base thereof. If the electrodes are utilized, a main electrode needs to be arranged only on the side of the photosensitive layer of the master, and developing liquid is supplied therebetween. The electrode is adapted to come into contact with the conductive base of the master, to thereby generate an electric field between the main electrode and the electrode. Therefore, the master can be directly injected with electrons instead of indirect injection, and adhesion of toner scum which often was caused in the prior art can be avoided. This further eliminates the trouble of cleaning the electrodes to improve maintenance.
