ABSTRACT:
Several rolls of a multi-roll magnetic brush development system are supported on brackets which have followers riding on the surface of the drum of an electrostatic processor to pivot the brackets about the axis of a first of the rolls in response to variations in the radial run-out of the drum. The bracket supported rolls may all be development rolls or one or more of them may be transport rolls. The significant feature is that the brackets maintain a constant roll-to-roll spacing, while the motion of the brackets tends to compensate for variations in the radial run-out of the drum or, in other words, to maintain a substantially constant photoreceptor-to-development roll spacing. Additional rolls may, of course, be mounted in series with the first of the rolls without encountering any variations in the roll-to-roll spacing because the brackets pivot about the axis of that roll.
