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 .
