Abstract

PURPOSE:To provide a titled machine of less color deviations by disposing a near parabolic optical transmission body array consisting of an assemblage of multiple near parabolic optical transmission bodies between an illuminating position and an exposure position of a photosensitive drum. CONSTITUTION:Color deviations are larger in the peripheral part of the optical device of a lens system, that is, in the parts further from the optical axis, and therefore only the image near the optical axis of the lens is utilized. Namely, a near parabolic optical transmission body array is used as a means for forming prescribed images. Now, in the 1st station I, the illuminating light illuminating an original in the 1st illuminating position C is imaged and exposed to a photosensitive drum 10 by a near parabolic optical transmission body array 2 and a multilayer film coated reflecting mirror 3. At this time, a desired wavelength is converted and selected by the mirror 3 in such a way that the moving direction of the light image conforms to a desired turning direction. In the 1st station I, for example, cyan exposure is accomplished, and similarly in the 2nd, 3rd stations II, III, exposure of magenta and yellow is accomplished respectively.
