Developing roller with novel structure

The utility model relates to a developing roller with a novel structure. The developing roller consists of a conductive head, a hard conductive tube, a soft conductive layer and a conduction head, one end of the hard conductive tube is connected with a conductive head; the other end is connected with a conduction head; and a soft conductive layer is wrapped outside the hard conductive tube. Compared with the prior art, the developing roller with the novel structure disclosed by the utility model has the advantages that through new structural design and material selection, the defects that an iron central shaft in the prior art is difficult to process, heavier in mass and high in total cost are overcome, and the developing roller can be more conveniently manufactured and complete preset functions. 本实用新型涉及一种新型结构显影辊，所述的显影辊由导电头、硬质导电管、软性导电层和传导头组成。所述硬质导电管一端连接有导电头；其另一端连接有传导头；所述硬质导电管外部包裹有软性导电层。与现有技术相比，本实用新型的新型结构显影辊通过新的结构设计和材料选择，克服了现有技术的铁质中心轴加工困难，质量较重和总成本高的缺点，可以更加方便的制造和完成预定功能。
