Abstract
An assembly for an electrophotographic image forming device according to one example embodiment includes a charge roll and a bracket that extends along an axial length of the charge roll. First and second bearing retainers are positioned on a first axial end and a second axial end of the bracket, respectively. First and second bearings are pivotally mounted to the first and second bearing retainers, respectively. Each of the first and second bearings has a charge roll opening that supports a respective axial end of a shaft of the charge roll. First and second biasing members act on the first and second bearings, respectively. The first and second biasing members bias the charge roll toward an operative position for charging a photoconductive drum. A direction of force from the first biasing member on the first bearing and from the second biasing member on the second bearing is toward the bracket.
