摘要： A device for developing an electrostatic latent image recorded on a photoconductive layer. The developing device comprises a doner roll for supporting a uniform layer of single-component developing material adjacent to the photoconductive layer. The doner roll is disposed as to create a space gap between the photoconductive layer and the doner roll. The doner roll is made of semiconductive material having a specific resistance ranging from 10.sup.6 to 10.sup.12 .OMEGA.cm. An electrical bias potential is applied across the gap, thereby establishing a field for transferring the developing material from the doner roll to the photoconductive layer.

摘要： An optical write head for an electrostatic dot-matrix image printing system which includes a plurality of controlled light emission element row-arrays positioned parallel and spaced in the direction perpendicular to the row-wise direction a distance equal to an integer multiple of the desired dot image-pitch S measured in the perpendicular direction, corrected by the fraction S/N where N is the number of row-arrays. A timed electrode drive circuit activates the arrays sequentially, and grid mask elements extending transversely across the row-arrays control emission from the individual light emission elements in an activated array, to minimize the number of drive circuit switching elements. A series-to-parallel signal conversion and storage circuit preprocesses the recording signal of the image to be printed.
