装置。 An exposure device for removing unnecessary charges on a photoreceptor by illuminating the photoreceptor includes a light source with a directing property, a deflection device for eliminating area patterning, and deflecting a luminous flux from the light source. Consists of a lens that forms an image of the light beam from the light source on the reflective surface of the polarizing device, and a field lens that allows the light beam from the deflection device to irradiate perpendicularly to the photoreceptor, and the photoreceptor and area diaphragm are conjugated. An exposure device characterized by being arranged in a relationship.
