電することを特徴とする変倍複写装置。[Claim for Utility Model Registration] Switching between a light-focusing fiber array for equal magnification and a light-focusing fiber array for reduction in order to form an original image on a photoreceptor at equal magnification or reduced magnification. In a variable-magnification electrophotographic copying device that is freely installed, the width of the light-focusing fiber array for reduction is set to be larger than the original width and the original image at the time of reduction, and the light-focusing fiber array is arranged so as to be larger than the original cover and the width of the original. A variable-magnification copying apparatus characterized in that a fiber array eliminates static electricity from a non-image area on a photoreceptor during reduction.
