Abstract

1411198 Cleaning xerographic apparatus INTERNATIONAL BUSINESS MACHINES CORP 7 Dec 1973 [26 Dec 1972] 56807/73 Heading G2H Charged toner particles 51, 52 are removed from the surface 11 of a xerographic drum by a wiper band formed from a compliant material having a resistivity not greater than 10<SP>8</SP> ohm centimetres that is moved in a closed loop to wipe the surface 11, while a cleaner device removes from the band particles transferred thereto and an electric current is applied to the band proportional to the image charge of the particles in contact therewith. The band may form the outer layer 35 of a roller 31 having a metal core 37 and a compliant foam layer 39, or it may be a belt 75 Figs. 3 and 4 respectively. The cleaner device may comprise a scavenger roller 41, Fig. 3, or a scraper blade 43, Fig. 4. The current supply source 47 may consist of a connection to earth where the toner particles 51, 52 are of mixed polarity, e.g. where they have been subjected to an A.C. pre-clean corona, but preferably the particles are subjected to a positive pre-clean corona and the current source 47 is at a low negative D.C. potential. The outer layer 35 of the roller 31 may be a carbon filler silicone rubber, or conductive forms of neoprene, polyurethane or ethylene/propylene copolymer. The specification also discloses suitable developer compositions for magnetic brush development of latent images on the xerographic drum.
