Abstract:
A toner for use in an image-forming apparatus which has an aperture electrode member for controlling the flow of a charged toner and a toner feeding means for feeding the charged toner to the aperture electrode member, where the aperture electrode member comprises an insulating sheet, a plurality of apertures formed at a specified position through the insulating sheet and a control electrode formed on the insulating sheet for each aperture, and the toner feeding means and the aperture electrode member are arranged such that a surface of the toner is in contact with the toner feeding means and an opposing surface of the toner is in contact with the aperture electrode member at the specified position where the toner is supplied through the plurality of apertures and so as to allow the charged toner to fly from the toner feeding means toward a recording medium by applying a voltage to the control electrode while passing through the aperture, said toner comprising:a core material that includes a binder resin; anda fine-powdered abrasive adhered to the surface of the core material, so as to facilitate passage of the toner through the apertures of the aperture electrode member.
