Electrophotographic image forming apparatus having a charge removing means

摘要

An image forming apparatus includes a rotatable photosensitive member including a conductive base and an organic photosensitive film located on a surface of the base and containing two charge generation materials which have different light absorbing characteristics from each other and different wavelengths showing a maximum light absorbance from each other; a charging device for charging the organic photosensitive film, the charging device being located in the vicinity of the photosensitive member; a charge removing member including a light source for radiating light toward the organic photosensitive film to uniformize the potential of a surface of the organic photosensitive film, the light having a wavelength in the range between wavelengths corresponding to half of a maximum light absorption of at least one of the two charge generation materials; an exposing device for radiating light corresponding to an image toward the organic photosensitive film charged by the charging device; and a developing device located downstream with respect to the exposing device in a rotation direction of the photosensitive member. The residual carriers in the organic photosensitive film are reduced, and thus the image quality is significantly improved.
