Abstract

In conventional electrostatic development a two component developer is used to produce frictional charging between the toner and carrier, In the instant .system carrier beads are eliminated, with all of the ensuing advantages of a single component development system. The primary develop~ ment mode is through the use of a vibration similar to vibrating bed development systems. However, a carrier coated electrode is substituted for the moving carrier

In conventional electrostatic development a two component
developer is used to produce frictional charging between
the toner and carrier, In the instant .system carrier beads
are eliminated, with all of the ensuing advantages of a
single component development system. The primary develop~
ment mode is through the use of a vibration similar to
vibrating bed development systems. However, a carrier
coated electrode is substituted for the moving carrier

beads, In order to minimize charge retention of the surface
coating on the electrode which comprises the toner container
the carrier coating is applied to the electrode in a random
size dot pattern leaving adjacent areas of the conducting
electrode uncoated. The coating used on the metal surfaces
has a controlled conductivity which will permit a slow
dissipation of accumulated charge, as toner is charged and
removed from the surface of the plastic.
