Abstract
In a reproduction apparatus having a rotatable imaging roller upon which an image is formed, and a rotatable transfer roller for transferring an image from the imaging roller to a receiver member, a device for mounting the transfer roller to substantially compensate for changes in engagement between the imaging roller and the transfer roller during image transfer. The mounting device includes a bearing assembly for supporting the transfer roller for rotation. A flexible member is associated with the bearing assembly. The flexible member provides movement of the bearing assembly by urging the bearing assembly in a direction to maintain, at least over a limited distance, the transfer roller in constant force engagement with the imaging roller so as to substantially prevent any change in the angular speed relationship therebetween.
