Abstract: The invention includes an apparatus 40 for developing a latent charge image formed on a photoreceptor 36 disposed on an interior surface of a faceplate panel 12. The apparatus 40 comprises a developer tank 42 having a sidewall 44 closed at one end by a bottom portion 46 and at the other end by a panel support 48 having an opening 50 therethrough to provide access to the faceplate panel 12. A back electrode 52 has a potential applied thereto to establish an electrostatic drift field between the back electrode and the photoreceptor 36, which is grounded. Triboelectrically-charged, dry-powdered, light emitting phosphor material, having a charge of the same polarity as the potential applied to the back electrode 52, is sprayed into the developer tank 42, between the back electrode 52 and the faceplate panel 12. The triboelectrically charged phosphor material is directed toward the photoreceptor 36 on the faceplate panel 12 by the applied electrostatic drift field.
