Abstract

1506011 Keeping electrophotographic screens clean CANON KK 17 Feb 1975 6597/75 Heading B6C In an electrophotographic apparatus of the kind in which a primary electrostatic latent image is formed on a movable apertured photosensitive screen 21 and used to modulate a charged particle flow to form a secondary image on a receiving member, the screen 21 is protected from dust by being enclosed by walls 84 which are open adjacent the image forming means. The apparatus may include cleaning brushes 46, 81 located in housings 47, 82 connected to suction means.
