Abstract

An applicator for a development unit is precisely positioned with respect to an image member, such as a photoconductive drum. A pair of pins are fixed with respect to the image member and fit in a pair of holes that are fixed with respect to the applicator. A roller on each of opposite ends of the applicator engages a surface of the image member to properly space the applicator and image member, while the pins and holes control relative lateral and rotational movement.
