Abstract
PURPOSE:To provide a compact device by providing predetermined reflectance and transmittance to the white color member of the margin former, forming a margin at the leading end part of a copy and preventing the loss of the quantity of lighting light to the effective image part of an original. CONSTITUTION:A lighting light source 6, a reflection mirror 7 for symmetrically lighting the original, and a flat-plate-like white color member 10 for creating a margin at the leading end of a copy are provided. Since the member 10 opposes to the leading end part of transfer paper, a margin part where no images are formed is assured there and since the shadow of the boundary of the part 3 to be abutted on an original 1 is held covered by the member 10, it does not appear in the image. Even at the lighting of the effective image part, the member 10 has predetermined transmittance owing to the direct lighting light from the light source 6 and this obviates the formation of lighting shadow.
