Abstract
According to the present invention, for example, there is slidably provided a CCD unit comprising a CCD and a plurality of filters in the light path of a lens block for magnification and reduction of a multicolor image forming apparatus, in which the CCD performs an irradiation scanning operation of an original using the plurality of filters in turn to sense the original image and then convert it into a series of electric signals which are used for color identification, the color identification data thus obtained being used to operate developing units selectively and an erasure array so as to form a multicolor image corresponding to the original.
