ABSTRACT:
An image forming apparatus which produces image data by reading an original document, modulates a light beam to be radiated from a light emitting element by the image data, and exposes an electrophotographic conductive element imagewise by the light beam modulated. The power of the modulated beam is varied dot by dot in association with tones. The apparatus renders multiple tones without lowering resolution.
