Patent ID: 6876827

Claim:
An improved electrical connection device for use in an image forming apparatus comprising of a printer, copy machine or a facsimile machine or a toner cartridge used therein to supply a bias voltage to a developer roller whereby a bias voltage contact fits into the developer roller whereby said bias voltage contact has a first portion that fits into the developer roller and whereby a second portion is cylindrical and rotates inside an electrobushing; whereby said electrobushing acts as an electrical contact and also as a bearing and has a bore sized to receive said second portion of said bias voltage contact; wherein a first end of said electrobushing makes electrical continuity with a power supply of the image forming apparatus; and a second end of said electrobushing receives said second portion of said bias voltage contact and thus said electrobushing makes electrical continuity with said second portion of said bias voltage contact; and thus said electrobushing not only acts as a bearing but also helps supply electricity to the developer roller.
