ABSTRACT:
An image combining apparatus for a digital color copier having a plurality of photoconductive drums each being assigned to respective one of yellow, magenta, cyan and black, and a delay memory for delaying data stored and associated with the individual colors to thereby register images of the individual colors. The delay memory plays the role of a frame memory. The apparatus is capable of combining an image of a black-white image stored in the frame memory in the form of black data and a color image of a color document, and combining a color image of a color document stored in the delay memory in the form of color data and a black-white image of a black-white document. These two different combinations are switched over to be effected one at a time, as desired.
