    摘要: An image forming apparatus including an image carrier, a charger, an electrostatic latent image forming member, a developing member, a transferor, and a cleaning device. The electrostatic latent image forming member forms an electrostatic latent image on a surface of the image carrier charged by the charger. The developing member develops the electrostatic latent image formed on the surface of the image carrier with toner particles to form a toner image. The transferor transfers the toner image formed on the surface of the image carrier onto a recording medium. The cleaning device includes a fine particle supplier and an electrostatic cleaning mechanism. The fine particle supplier supplies fine particles onto the surface of the image carrier while an image forming operation is not performed. The electrostatic cleaning mechanism electrostatically removes a foreign substance adhered to the supplied fine particles from the surface of the image carrier.

    摘要: A cleaning device removes residual toner particles from a cleaning target, such as a photoconductor, which has a moving surface. The cleaning device includes a cleaning brush, a power circuit, and a cleaning member. The cleaning brush includes a brush rotation shaft, and the power circuit applies a first voltage of a first polarity to the brush rotation shaft. The cleaning member applies a second voltage of the first polarity to the cleaning brush. If the first polarity is negative, the cleaning member electrostatically removes toner particles having a positive polarity from the cleaning target. Then, the cleaning brush is triboelectrically charged to a second polarity, which is opposite to the first polarity, by contacting the cleaning target. Accordingly, the cleaning brush also removes residual toner particles having a negative polarity. Thus, the cleaning device removes both positively and negatively charged toner particles to clean the cleaning target.
