FULL-COLOR XEROGRAPHIC PRINTING SYSTEM PROVIDED WITH DOUBLE WAVELENGTH SINGLE OPTICAL SYSTEM ROS AND DOUBLE LAYER PHOTOSENSITIVE BODY

摘要

PURPOSE: To provide a double wavelength-sensitive and double photosensitive layer type xerographic printing system capable of taking either double paths or a single path. ;CONSTITUTION: This printing system is provided with a raster output scanning optical system for generating the first modulated beams 120 and 121 as one of a first wavelength and second modulated beams 122 and 123 as one of a second wavelength, a photosensitive means provided with a first layer capable of sensing or accessing only the first wavelength and a second layer capable of sensing or accessing only the second wavelength and a xerographic means for charging the photosensitive means, then exposing the area of the photosensitive means to one or both or neither of the first modulated beams 120 and 121 and the second modulation beams 122 and 123, sticking different color toner to the photosensitive means in response to the exposure of the area of the layer to the modulated beams after the exposure and obtaining black and white and all six primary colors.;COPYRIGHT: (C)1994,JPO
