Abstract

1322681 Electrostatic printing XEROX CORP 3 Jan 1972 [6 Jan 1971] 130/72 Heading G2H In an electrostatic printing machine the photosensitive drum 12 makes two revolutions for every copy printed, the first revolution of the drum, representing phase I, being used for making sure that a donor roller used for powder developer carries an even layer of powder for subsequent use in the printing revolution representing phase II. The machine is controlled by a cyclic controller 20 such that driving the donor first revolution any old toner is removed from the roller and a fresh toner coating applied whilst the photo-sensitive drum is charged. During the second revolution a latent image is formed on the drum, the toner bath tray is dropped away from the donor roller. The latent image is developed by the donor roller and the resulting visible image transferred to a web at F.
