• sensing the portion of the original which has been marked over and creating a signal indicative to the location of that portion on the original;
• placing the original in an exposure position;
• while the original is in the exposure position, creating two electrostatic images by twice exposing at least one charged photoconductive member with an image of the original, the spectral characteristics of the photoconductive member and of the exposing illumination being such that the photoconductive member does not respond substantially differently to the spectral reflectance of the marking material than it does to the noninformation areas of the original;
• erasing portions of said electrostatic images as controlled by said signal, to create an image corresponding to the marked over portion of the original and an image corresponding to the rest of the original;
• toning the electrostatic images with different color toners;
• and
• transferring the two toned images to a receiving medium in registration to create a reproduction of the original with the portion corresponding to the marked over portion being a different color than the rest of the reproduction.

A method of reproducing a document sheet comprising:

• providing the document sheet having original image information with indicia placed over or around a portion of original image information indicating image areas to be reproduced in a color different from that used to reproduce the remaining information on the document sheet;
