APPARATUS AND METHOD FOR FORMING MULTICOLOR ELECTROPHOTOGRAPHIC IMAGES

摘要

A plurality of constituent electrostatic color-separation images are produced in sequence for subsequent toner-development and superimposition and at least one developed constituent image is used to color-correct a succeeding constituent image which is not yet developed. Apparatus and method embodiments described herein utilize light which is diffusely-reflected from toner on a developed photoconductor image sector to expose in register, and thus color-correct, an undeveloped electrostatic image on another photoconductor sector. Such auxiliary "scatter-masking" exposures can be predeterminedly or selectively adjusted in tone scale.
