A device for exposing an edge zone of a photoconductive element to light comprising a light source and a moveable screen by means of which the width of the edge zone that is exposed to light can be adjusted. The light source is fixed to the moveable screen and is moveable therewith. Preferably, the screen consists of a pivotable housing in which the light source is mounted in an area defined by two planes which intersect along the bottom edge of the innermost side wall of the housing and form an angle of 15.degree. such that the plane through the pivot line of the housing and the bottom edge of the innermost side wall of the housing bisects the 15.degree. angle.
