ABSTRACT:
A device for erasing charges from an area of a charged electrophotographic image-bearing member includes a light source mounted on an electroluminescent (EL) panel which has a slot and semi-transparent members that project partially into the slot. Light from the source is restricted to passage through the slot where the semi-transparent members serve to reduce the intensity of part of the light resulting in light of different intensities impinging on the area being erased.
