Method for forming overlapping toner images

摘要

First and second toner images (usually of different color) are formed which at least partially overlap. The first toner image is crated by electronically exposing, pixel-by-pixel, a uniformly charged image member, to create a first electrostatic image and toning that image with toner of a first color. A second electrostatic image is formed by electronically exposing the image member according to a second electronic signal. The exposure of each pixel in the second exposure is adjusted to compensate for a change in electric field caused by any presence of toner from the first exposure in that pixel. The second electrostatic image is toned by toner of a second color to create a multicolor image with portions that overlap.
