Abstract

PURPOSE:To prevent the occurrence of black solid copies caused by exposure defects, by providing a light emission detecting means detecting that an exposure lamp normally emits light and operating an eraser provided ahead of a developing unit over the full width of a photosensitive body when light emission is not detected. CONSTITUTION:When an original is fed to a contact glass 102, recording sheets of size suitable for said original are fed from trays 113 - 115. In parallel with the feeding of recording sheets, the exposure lamp of an exposing device 101 lights up to rotate a photosensitive body 107, and latent images in response to the original contents are formed on the surface of the photosensitive body. When the light emitting lamp does not emit light when exposure is required, the eraser 109 provided ahead of a developing part 110 fully lights up, and an electrostatic charger 108 removes electrified charges on the surface of the photosensitive body 107. As a result, the developing part 110 prevents toner from sticking to the surface of the photosensitive body 107, thereby eliminating black solid copies.
