    • A method for manufacturing a cathode comprises the steps of: a process for applying onto a substrate a fluid mixture comprising polymers or precursors to the polymers, fine particles of electroconductive material or organic metal compound, and solvent; a process for removing the solvent by heating the fluid mixture applied on the substrate, thereby obtaining an electroconductive organic film comprising the polymers and the electroconductive material; and a process for forming a gap at a portion of the electroconductive organic film by applying an electrical current thereto. Accordingly, a simple method for manufacturing cathodes, electron sources, and image forming apparatuses with excellent electron emitting properties can be realized.
    • 一种用于制造阴极的方法包括以下步骤:将在聚合物上包含聚合物或前体的流体混合物,导电材料或有机金属化合物的细颗粒和溶剂施加到基底上的方法; 通过加热施加在基板上的流体混合物来除去溶剂的方法,从而获得包含聚合物和导电材料的导电有机膜; 以及通过向其施加电流在导电有机膜的一部分处形成间隙的工艺。 因此,可以实现用于制造具有优异的电子发射特性的阴极,电子源和图像形成装置的简单方法。
