Abstract: A touchdown development system includes a donor roll (24) for positioning adjacent a photosensitive member in (10) order to develop an image on the surface of the photosensitive member. A «C-shell» toner housing (26) is positioned around the donor roll (24) to extend from the 6 o'clock to 9 o'clock position and filled with single component toner (28) and about 1% aerosil. A stationary and open mesh screen (30) is placed adjacent the donor roll so that a dense, uniform layer of well charged toner is formed on the donor roll for transfer to the photosensitive member surface. The screen leaves contact with the donor roll at a distance above the top of toner bath to thereby remove any excess toner from the donor roll surface.
