Abstract: PROBLEM TO BE SOLVED: To solve the problem that it is difficult to release an electroconductive roller having an electroconductive elastic layer, which is hard to cause image irregularity or the peeling of an end part and characterized in that the outer diameter of the central part of the electroconductive elastic layer in the longitudinal direction of the roller is increased and the outer diameters of the end parts thereof are reduced, in molding using a general mold and, if the electroconductive roller is formed by a grinding method, the adhesion of grinding refuse or a grinding mark occurs. SOLUTION: In manufacturing the electroconductive roller having a metal support member and the electroconductive elastic layer formed by curing a resin composition on the metal support member and characterized in that the outer diameter of the central part of the electroconductive elastic layer is larger than that of at least one end part thereof by 5-100 μm, a mold wherein the end parts thereof have an inner diameter smaller than that of the central part thereof is used to perform molding in a low airtight state.

Abstract translation: 要解决的问题为了解决难以释放导电性弹性层的导电性辊难以引起图像不规则或端部剥离的问题，其特征在于， 导电弹性层在辊的纵向方向上的中心部分增加，并且其端部的外径在使用一般模具成型时减小，并且如果通过研磨方法形成导电辊，则粘合力 研磨垃圾或研磨标记发生。 解决方案：在制造具有金属支撑构件的导电辊和通过在金属支撑构件上固化树脂组合物而形成的导电弹性层，其特征在于，导电弹性层的中心部分的外径大于 其至少一端部为5〜100μm的模具，其端部的内径小于其中心部分的内径，用于在低气密状态下进行成型。 版权所有（C）2005，JPO＆NCIPI
