Abstract

1302922 Removing toner particles ADDRESSOGRAPH-MULTIGRAPH CORP 26 Jan 1970 [27 Jan 1969 9 Dec 1969] 3673/70 Heading G2H Residual toner particles are removed from a biased transfer roller 78 or a photo-conductive belt 30 by magnetizable particles which attract the toner particles triboelectrically. The magnetizable particles are fed from reservoirs 96 and 96a respectively by cleaning rollers 100 and 100a, each having a stationary permanent magnet (102 and 102a), Fig.2 (not shown).
