Toner cartridge, contact device and method for developer roller and toner cartridge used therein |
摘要 |
An image forming apparatus or toner cartridge component thereof uses a bias voltage contact device that fits into an electrobushing which transmits the electrical contact has been invented. Thus, now a bushing can also act as an electrical contact and thereby a spring is not a requirement. The cylindrical bias voltage contact fits into a developer roller and has a smaller portion that is also cylindrical and fits into an electrobushing. The electrobushing is contacted electrically to the power supply of the image forming apparatus. The cylindrical bias voltage contact may have a cylindrical portion that fits into the developer roller by press fit with the new feature where the cylindrical portion has more than one diameter for obtaining a better press fit.
