Electrical connection for an imaging component of an electrophotographic image forming device

An assembly for an electrophotographic image forming device, comprising:

• a rotatable photoconductive drum;
• a rotatable charge roll having an electrically conductive shaft, an outer surface of the charge roll contacts an outer surface of the photoconductive drum along a length of the photoconductive drum;
• a cleaner blade in contact with the outer surface of the photoconductive drum along the length of the photoconductive drum for removing residual toner from the outer surface of the photoconductive drum;
• an electrically conductive bracket, the cleaner blade is mounted to the bracket and extends from the bracket toward the photoconductive drum;
• and
• an electrical contact positioned to receive an electrical voltage from a power supply of the image forming device, the electrical contact is electrically connected to a first end portion of the shaft of the charge roll by way of a first electrical path and electrically connected to a second end portion of the shaft of the charge roll by way of a second electrical path to transfer the electrical voltage to the charge roll for charging the outer surface of the photoconductive drum, the second end portion of the shaft of the charge roll is positioned opposite the first end portion of the shaft of the charge roll, the is bracket forms a portion of the second electrical path such that the electrical voltage transferring from the electrical contact to the second end portion of the shaft of the charge roll passes through the bracket.

A replaceable unit for use in an electrophotographic image forming device, comprising:

• a rotatable photoconductive drum;
• a rotatable charge roll having an electrically conductive shaft, an outer surface of the charge roll contacts an outer surface of the photoconductive drum along a length of the photoconductive drum;
• a cleaner blade in contact with the outer surface of the photoconductive drum along the length of the photoconductive drum for removing residual toner from the outer surface of the photoconductive drum;
• an electrically conductive bracket, the cleaner blade is mounted to the bracket and extends from the bracket toward the photoconductive drum;
• and
• an electrical contact exposed on the replaceable unit for mating with a corresponding electrical contact in the image forming device when the replaceable unit is installed in the image forming device to receive an electrical voltage from the corresponding electrical contact in the image forming device, the electrical contact of the replaceable unit is electrically connected to a first end portion of the shaft of the charge roll by way of a first electrical path and electrically connected to a second end portion of the shaft of the charge roll by way of a second electrical path to transfer the electrical voltage to is the charge roll for charging the outer surface of the photoconductive drum, the second end portion of the shaft of the charge roll is positioned opposite the first end portion of the shaft of the charge roll, the second electrical path includes the bracket.
