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.
An electrophotographic exposure and development arrangement comprising an image exposure unit having a curved belt support surface for supporting a moving transparent flexible photoreceptor belt at an image position at which the belt is exposed to imaging light by the image exposure unit on one side and at a development position spaced in the direction of motion of the belt from the image exposure position and a development unit disposed in spaced relation to the curved belt support surface on the opposite side of the flexible photoreceptor belt for applying toner to an electrostatic charge image on an adjacent surface of the photoreceptor belt while it is supported by the curved surface.
