PURPOSE:To enable to print and record the color corresponding to each of chroma information to be read in, by reading the different chroma information between the optical scanning at forward motion and the optional scanning at backward motion, in the read-in of plural chroma information through reciprocating operation. CONSTITUTION:The image forming device 100 consists of the read-in section 101 reading-in the information from the original held on the original stand 103 and the write-in section 102 writing in the read-in information on the recording paper 117, and the section 101 is provided with the detectors 114, 115 detecting the home and return positions of the moving mirror. Further, the beam splitter 109 is provided in the optical path incident to the photodetectors 110-1 and 110-2 to enable to discriminate two colors with the detectors 110-1 and 110-2. Further, the section 102 is located with the rotary drum 121 which can turn the recording paper 117 by two times and two sets of ink jet heads 122R, 122B printing different color, and according to the forward-and backward-operation of the section 101 for optical scanning, the heads 122R, 122B are switched, enabling two color prints. |
