Abstract
1384568 Electro-photographic apparatus ZELLWEGER USTER Ltd 25 July 1972 [16 Aug 1971] 34714/72 Heading G2H In a magnetic brush type developing apparatus in which a latent image on a label 127 contacts charged particles at the top 124 for rotating 'brush' 115 the developer mix pattern on the rotating drum 106a is established by a stationary permanent magnet core 116 having poles of successive polarity such that they alternate except for the two adjacent the top 124. The mix is supplied to the brush by a bucket wheel 113.
