Title: Electrophotographic exposure and development arrangement

Abstract: In the embodiment disclosed in the specification, an electrophotographic exposure and development arrangement has a flexible transparent photoreceptor belt driven between two support rollers and along four printing stations at each of which the photosensitive surface of the photoreceptor is charged, exposed to a light image corresponding to a selected color, and developed with toner of the corresponding color to produce a composite multicolor image which is transferred to a substrate and subsequently fixed on the substrate. At each printing station an exposure unit has a curved belt support surface which is engaged by the photoreceptor belt passing through the printing station between the exposure location and a development location with a curvature and length selected to minimize the effect of ripples or irregularities in the position of the photosensitive surface of the photoreceptive belt resulting from a set taken by the photoreceptor belt when held stationery against a supporting number.
