Abstract:
A charging device for charging a photoreceptor of an image forming apparatus so that a latent image is formed thereupon to be developed by toner, the charging device comprising:a charging roller for constantly contacting the photoreceptor with pressure so as to be rotated by rotation of the photoreceptor, said charging roller charging the photoreceptor; and a charging roller cleaning member for constantly contacting a surface of the charging roller with pressure so as to remove toner transferred onto the charging roller from the photoreceptor, wherein a length portion of the charging roller cleaning member along an axial direction of the charging roller is set to be equal to or greater than a width portion of an effective development area in an axial direction of the photoreceptor and smaller than a charging contact width portion of the charging roller with the photoreceptor in the axial direction of the charging roller.
