Abstract

1523325 Magnetic brush development XEROX CORP 15 Oct 1975 [20 Nov 1974] 42243/75 Heading B2L In a magentic brush development system the developer rolls 51-54 are mounted on a pivoted spring biased bracket that also carries a follower roll 87 bearing on the drum 15. The motion of the bracket thus follows variations in the radial run-out of the drum so that there is a constant spacing between the rolls and the drum. The housing of the system comprises two relatively-movable sections one of which includes a developer mixer see Specifications 1521775 and 1521776.
