In order to provide an image forming apparatus capable of making potential control executable immediately after starting copying and shortening a first copying time, the image forming apparatus is provided with a photosensitive drum (1), a charging magnetic brush charger (2) for charging the photosensitive drum (1) and a main electricity eliminating light irradiating apparatus (8) for irradiating light to eliminate a light memory in the photosensitive drum1. Further, in the image forming apparatus, the main electricity eliminating light irradiating apparatus (8) irradiates the photosensitive drum (1) with an exposure amount larger than a minimum exposure amount for eliminating a light memory in at least a part of an irradiation process.
