For a long time, most people only care about the more common cartridge components such as drum cores and toner. However, the quality of the charging roller also has an important impact on the quality of the cartridge!

Of course, low-cost toner cartridges certainly do not have so much protection. Many times the bottom ash on the printing paper is often caused by poor charging rollers.
