Color resolved latent electrostatic images are formed by scanning an original through water separation filters, converting the color resolved images of the original into digital data, feeding the data into a computer 15 and then writing the images on the surface of a charged electrophotographic drum 21 with a laser 19 whose output is modulated by the digital data. During each revolution of drum 21 one color image is written, toned and transferred to receptor 5 on which the images are superimposed. The developing device 43 includes a plurality of developing units, each containing a different color toner, which are moved past the drum 21, seriatim in a stepwise cycle. Movements are coordinated so that each developing unit will apply toner to its corresponding latent electrostatic image during a dwell period of the developing device when said developing unit is in toner- applying relation with the drum. <IMAGE> |
