Abstract
A magnetic brush developer apparatus for developing an electrostatic charge pattern on a member by contacting the member with particulate magnetic developer material, such material being contained within the zone of contact to prevent uncontrolled escape from the zone and contamination of the environs. The apparatus includes an applicator for transporting developer material in a non-agitated state into contact with the charge pattern on the member. A portion of the developer material in contact with such charge pattern is magnetically agitated to form in such material an agitated zone bounded by the non-agitated material to establish a sealing zone about the agitated zone.
