Abstract
An apparatus for driving edge-emission type electroluminescent elements to emit light to expose an image carrier and to form image data clearly on the image carrier. The edge-emission type electroluminescent elements have electrodes and emit light when a potential difference across the electrodes exceeds a preset threshold value. Electric pulses are supplied to the electrodes of the edge-emission type electroluminescent elements to cause the potential difference across the electrodes to exceed the preset threshold value so that the edge-emission type electroluminescent elements emit light. A series of pulses are supplied for each pixel of image data. The series of pulses includes a first set of pulses supplied at a first cycle to cause the edge-emission type electroluminescent elements to emit light to expose the image carrier, and a second set of pulses supplied at a second cycle slower than the first cycle to cause the edge-emission type electroluminescent elements to emit light to maintain exposure of the image carrier.
