ABSTRACT:
Image formation and development apparatus using electrostatic techniques which is suitable for plain paper printing is provided wherein a cathode ray pin tube is used with a flexible discontinuous dielectric member that is moved past the pin tube, the selectively energized pins providing information-bearing areas (i.e. toner attracting areas) on the dielectric member; the latent electrostatic image is developed and may thereafter to transferred to plain paper and fixed for subsequent use. The apparatus includes pin tube cleaning means operative when the belt discontinuity passes the pin tube face.
