Abstract
A two-color copying apparatus has a half reflecting mirror located posterior to an image forming lens in the path of a light beam for splitting a light beam reflected by an original in black and a chromatic color for development of corresponding latent images on respective photoconductive drums and printing on a transfer-printing sheet conveyed by a conveyor belt and successively brought into contact with the outer circumferential surfaces of the drums. The sub-beam of light reflected by the half reflecting mirror and the sub-beam of light transmitted through the half reflecting mirror serve as a chromatic color image forming sub-beam of light and a black image forming sub-beam of light, respectively, which are projected on to quadrants on the outer circumferential surfaces of the two drums located on opposite sides of the drums with respect to imaginary vertical lines extending through the centers of the respective drums which are remote from the positions in which the transfer-printing sheet is brought into contact with the drums.
