Imaging system for a photocopying device

Claim 1

Image forming apparatus including a stationary illumination source, said apparatus comprising: belt means for moving a document past said illumination source, said illumination source being disposed adjacent one side of said belt; means positioned to said one side of said belt for projecting a light pattern reflected from said document along an optical path; a photoreceptor having a uniform, electrostatically charged portion positioned in said optical path whereby said light pattern impinges upon an area thereof and causes the charged portion to be discharged in accordance with said light pattern; and specular reflector means positioned adjacent the opposite side of said belt to reflect illumination from said source adjacent all the edges of said document along said optical path whereby illumination strikes said uniformly charged portion in an area adjacent the area struck by said light pattern, said illumination being sufficient to discharge said adjacent area, said specular reflector comprising a first set of planar surfaces each disposed at predetermined angles relative to said belt and a second set of planar surfaces each disposed at predetermined angles relative to said belt such that the planar surfaces of said first set are substantially perpendicular to lines which pass through a first reference point and said planar surfaces of said second set are substantially perpendicular to a plurality of lines all of which pass through a second reference point.
