摘要： After a toner image is transferred from a photoreceptor to an intermediate transfer belt, a surface of the photoreceptor is destaticized by a static eraser including a plurality of light emitting elements arranged in an axial direction of the photoreceptor. A first density sensor and a second density sensor for detecting densities of toner applied to the intermediate transfer belt are provided at a position where a large quantity of light from the static eraser is applied to the photoreceptor surface and a position where a small quantity of light from the static eraser is applied to the photoreceptor surface. In a case where a density difference between the detected toner densities exceeds a predetermined threshold value, a destaticization controller carries out an additional destaticizing operation by the static eraser.
