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.
摘要翻译：液晶电子照相显影方法，其中电极仅布置在母版的感光层的一侧，显影液被供应在母体和电极之间，并且使导体与母版的基部接触，使得电在感光平面和用于显影的电极之间产生场。用于电子照相显影方法的电极包括多个导线，它们沿与材料的行进方向垂直的方向布置成与其导电基底接触。如果使用电极，则主电极仅需要布置在母板的感光层的一侧，并且在其间供应显影液。电极适于与母板的导电基底接触，从而在主电极和电极之间产生电场。因此，主体可以直接注入电子而不是间接注入，并且可以避免在现有技术中经常引起的调色剂浮渣的粘附。这进一步消除了清洁电极以改善维护的麻烦。

摘要： A process for producing a printing plate and a printing plate making machine are disclosed. The process involves providing an electrophotographic plate making material which includes a base having a low conductive layer thereon. The material is electrically charged and imagewise exposed. The imagewise exposed material is subjected to liquid toner development with a toner containing a solvent. The solvent is then substantially removed by heating the material to a temperature sufficient to cause the evaporation of the solvent. The material is then moved to a substantially isolated fixing area and again heated in order to fix a toner image on the plate making material. The process can be quickly and easily carried out and eliminates the danger of the explosion of solvent vapors.
