Positioning features and electrical contacts for a replaceable unit of an electrophotographic image forming device

A photoconductor unit for an electrophotographic image forming device, comprising:

• a housing having a top, a bottom, a first side and a second side formed between a first end and a second end of the housing, a first end wall is positioned at a first end of the housing;
• a photoconductive drum mounted on the housing having a rotational axis that runs from the first end to the second end;
• a first flexible metal tab extending axially inward with respect to the photoconductive drum from an inner axial side of the first end wall, the inner axial side of the first end wall faces toward the second end of the housing, the first flexible metal tab is exposed on the inner axial side of the first end wall to contact and force a developer unit toward the second end of the housing when the developer unit is operably mated with the photoconductor unit and to contact and form an electrical path with a corresponding electrical contact on the developer unit when the developer unit is operably mated with the photoconductor unit;
• and
• a second flexible metal tab extending axially outward with respect to the photoconductive drum from an outer axial side of the first end wall, the outer axial side of the first end wall faces away from the second end of the housing, the second flexible metal tab is exposed on the outer axial side of the first end wall to contact a plate in the image forming device and force the photoconductor unit axially with respect to the photoconductive drum in the direction of the second end of the housing when the photoconductor unit is installed in the image forming device and to form an electrical path with the plate when the photoconductor unit is installed in the image forming device,
• wherein the second flexible metal tab is electrically connected to a circuit of the photoconductor unit that includes the photoconductive drum to electrically ground the circuit of the photoconductor unit to the plate when the photoconductor unit is installed in the image forming device.

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

• a photoconductor unit portion that includes a photoconductive drum having a first rotational axis that extends from a first end of the replaceable unit to a second end of the replaceable unit;
• a developer unit portion that includes a reservoir for storing toner and a developer roll having a second rotational axis that extends from the first end of the replaceable unit to the second end of the replaceable unit, an outer surface of the developer roll is positioned along an outer surface of the photoconductive drum to deliver toner from the reservoir to the photoconductive drum;
• and
• an electrically conductive first biasing member positioned between the photoconductor unit portion and the developer unit portion forcing the developer unit portion axially with respect to the photoconductive drum toward the second end of the replaceable unit and forming an electrical path between a first electrical contact on the developer unit portion and a second electrical contact on the photoconductor unit portion.
