PURPOSE: To form an image where a black-and-white image and a color image coexist without a hindrance even in the case a transmissive sheet or plain paper is used by unifying output information separated for every image forming means while deciding the kind of a recording medium. CONSTITUTION: When image data is inputted from an external device 29, it is separated to the text black-and-white image, the black-and-white graphics and the color image by an image separation means C6 and stored in RAMs 1 to 5, and the kind of the recording medium is discriminated by a photointerrupter 25. In the case the recording medium is an OHP sheet and color image data is included in image-forming, the ROM 2 storing an image forming mode for an OHP sheet is read in first, and the stored content in the RAM 1 is transferred to the RAM 5 so that the image-forming of the black-and- white image data previously separated is performed by an ink-jet system. Thus, the image-forming is performed in a state where the black-and-white image coexists with the color image by the ink-jet system without contaminating a 2nd image forming means B by an electrophotographic system. |
