Abstract
Magnetic brush developer apparatus for selectively developing an electrostatic charge pattern on a member by contacting the member with particulate magnetic developer material. The apparatus includes an applicator for transporting developer material in juxtaposition with such member. An electromagnet is operatively associated with the applicator for establishing developer nap bristles on the applicator when energized. The electromagnet is selectively energized to establish nap bristles to develop a selected electrostatic charge pattern with developer material and deenergized to avoid development of any non-selected electrostatic charge pattern.
