[0002] Organic photoconductive drum is the "heart" component of electrophotographic imaging that can form and migrate photogenerated carriers under light excitation. In 1998, the world's OPC production was 110 million units, which has generated huge economic and social benefits. The corresponding and related industries have become sunrise industries with an annual growth rate of over 15%. The structure of OPC drum can be divided into four layers according to its function: conductive substrate, barrier layer, photogenerated carrier generation layer, photogenerated carrier transport layer, etc. Some of them are also coated with a protective layer on the outermost surface.

[0003] Currently, gears are installed at both ends of the organic photoconductive drum. When the gears are installed in a printer or other equipment, the gears at both ends of the organic photoconductive drum are installed through a snap-fit ​​structure. When disassembling, the gears and the organic photoconductive drum must be removed from the printer or other equipment first before the organic photoconductive drum can be removed from the gears. This disassembly method requires two disassemblies, which is more troublesome. Utility Model Content
