Abstract

1382143 Developing apparatus RANK XEROX Ltd 3 March 1972 10046/72 Heading G2H The image on the photo-conductive surface of a rotary drum 4 is developed in a mixture of toner powder 5 and liquid carrier 8. The carrier is directed on to the lower surface of an inclined guide plate 3 by a rotating vaned wheel 1 and as it passes the aperture 6 in the toner reservoir some carrier enters the reservoir and entrains toner into the carrier stream. Means for assisting the feed of toner to the aperture 6 may be as described in Specification 1382142 (Heading G2H). The developer may comprise liquid carrier and toner, particulate toner and carrier or liquid carrier and particulate toner.
