摘要： An ionographic printer directs a stream of ions from a source to a charge receptor to create an electrostatic latent image thereon. The ion stream passes through a relatively large aperture having associated therewith a pinch electrode for narrowing the ion stream to a preselected width, and displacing electrodes for positioning the narrowed ion stream within the aperture. Varying the biases of the displacing electrodes causes the ion stream to scan across the aperture to deposit multiple spots of charged areas at desired locations on the receptor. The electrodes can be designed to compensate for spot placement skew and anomalies in the cross-sectional shape of the displaced ion stream.

摘要： An ionographic printer directs a stream of ions from a source to a charge receptor to create an electrostatic latent image thereon. The ion stream passes through a relatively large aperture having associated therewith a focusing pinch electrode for narrowing the ion stream to a preselected width, displacing electrodes for positioning the narrowed ion stream within the aperture, and focus electrodes. Varying the biases of the displacing electrodes causes the ion stream to scan across the aperture to deposit multiple spots of charged areas at desired locations on the receptor. Varying the biases of the focus electrodes cures positional and ion-stream cross-section anomalies.

摘要： In the development of xerographic images wherein the latent image is in the form of a periodic charge pattern, polar or polarizable toner particles are employed. It is desirable to utilize a development system that will bring the polar or polarizable toner into contact with the periodic charge pattern without triboelectrically charging the particles. To achieve this aim, an apparatus and method are described for moving the polar or polarizable toner particles through a development zone at substantially the same speed and in the same direction as that of the imaging member.

摘要： A multi-color printer using a stretch toner release development system to provide either partial or full color copies with minimal degradation of developed toner patterns by subsequent over-development with additional colors and minimal back contamination of developer materials. Multiple scanning beams, each modulated in accordance with distinct color image signals, are scanned across the printer's photoreceptor at relatively widely separated points, there being a buffer provided to control timing of the different color image signals to assure registration of the color images with one another. Each color image is developed prior to scanning of the photoreceptor by the next succeeding beam. After developing of the last color image, the composite color image is transferred to a copy sheet. Development is accomplished by stretching the surface of a toner carrying member and thereby reducing the net force of adhesion of toner to the surface of the toner carrying member.
