Abstract

A two-color copying machine includes a scanner unit for simultaneously generating signals representing different colors on an original document and first and second thermal head assemblies each responsive to signals representing a different color image for recording two different color images on a single recording sheet. If desired, only one of the color portions of the original may be recorded, or they can both be recorded in a single recording color.
