ABSTRACT:
An image forming apparatus provided with a blank exposure device. The blank exposure device includes a plurality of light sources, each of which exhibits a light directivity. The light emitted from the directive portion is effective to electrically discharge the non-imaging area of the image bearing surface. Only adjacent to that side of each of the light emitting sources, such as light emitting diodes, which is nearer to the imaging area of the image bearing member, there is provided a light blocking member to block the light emitted from the marginal portion of the light-directive portion of the light emitting element.
