Abstract
A replaceable development station usable for developing electrostatic images in apparatus having a toner monitor and a device for slidably receiving the development station includes a chamber containing a supply of a development mixture of toner and carrier particles. A recess is defined in one wall of the chamber for receiving the toner monitor, the recess being defined by a thinned region of the wall such that the toner monitor is separated from the developer mixture by a wall region substantially thinner than the general wall thickness. A device is provided for camming the development station tightly against the toner monitor and clamping it there such that the resilient force needed to maintain contact is minimized.
