Abstract

1,127,830. Printing processes. CONTINENTAL CAN CO. Inc. 7 Oct., 1966 [24 Oct., 1965], No. 45036/66. Heading B6C. [Also in Division G2] An apparatus for electrostatic printing comprises a drum 10 having recessed image areas 18 which receive toner 22 supplied by a powder cloud generator 23. Toner from the image area is transferred electrostatically to a substrate 42. A corona device 26 charges the toner 22 which forms a coating on the image 18 and non-image 16 areas. A doctor blade 30 removes substantially all the toner from the non-image areas, the remainder being removed by rollers 32. A corona device 38 recharges the toner in the image areas before transfer to the; substrate oppositely charged by a corona device 60. In a modification, non- image area (16), Fig. 2 (not shown), has a dielectric coating 70 charged negatively by a corona device 72, such that negatively charged toner is repelled from the non-image area.
