Abstract

A fully articulated magnetic brush development apparatus for developing images on a moving imaging surface such as a xerographic drum. The development apparatus includes a housing 44 which supports a magnetic brush development roll (shown in phantom) for applying developer to the drum sur~ face. The gap between the development roll and the drum is maintained constant from side-to~side by mounting the housing both for movement toward and away from the drum sur- £ace and for side-to-side tilting movement. The housing is supported by means of pins 40 at each side and pin 41 at its rear. A spring 47 biases an inclined plane member 48 which
