Abstract

1486688 Developing electrostatic images KONISHIROKU PHOTO INDUSTRY CO Ltd 9 July 1975 [9 July 1974] 28924/75 Heading G2H A development electrode, which may be the rotating outer sleeve of a magnetic brush, the stationary outer sleeve of a applicator with a rotating magnetic core or a rotating sleeve over a counter-rotating magnetic core, or alternatively may be an electrode in a cascade development apparatus, has an insulating coating on its surface facing electrostatic images to be developed. The coating is stated to prevent flaws and scores in a photo-conductive surface from producing corresponding marks in developed images.
