Abstract: PURPOSE:To permit almost an infinite kind of color designation, and to obtain a monochromatic copy with a designated color by designating a prescribed color, and performing the density modulation of a color primary signal having a mixing ratio decided by a mixing ratio deciding means with an achromatic color density signal. CONSTITUTION:When the monochromatic copying is performed with the designated color, a monochromatic color pressing part 4 is functioned.
