Abstract

1332925 Electro-photographic printing apparatus XEROX CORP 2 Nov 1970 [6 Nov 1969] 51970/70 Heading G2H In order to ensure that superfluous toner remaining after development on the non-image areas of a toner carrying plate is not removed by the copysheet during image transfer a knifelike electrode 11 corona charging device is applied to the developed plate, a grounded shield member 10 being located around the electrode such that corona emissions repelled by the charged toner covered imaged areas of the plate are absorbed by the shield member.
