ABSTRACT:
An image forming apparatus is provided with a light emitting element for indicating a specific range of an original disposed on an original table, and the other light emitting elements for erasing the electric charge on the surface of a photosensitive body in response to the specific range of the original indicated by the light emitting element. A spot light is applied to the original on the original table by the light emitting element, and moved to specify an erasure range. In image forming, a light beam is applied to a photosensitive body in response to the specified erasure range to erase an electrostatic latent image or electric charge thereon by the other light emitting elements.
