摘要： An image forming apparatus includes a charger, a developing device, a cleaning device, a protective-agent bar, and a brush. The charger uniformly charges an image carrier. The developing device develops an electrostatic latent image formed on the image carrier to obtain a toner image as a visual image. The cleaning device removes toner remaining on the surface of the image carrier from which the toner image has been transferred onto a transfer material. The protective-agent bar contains a protective agent. The brush comes in contact with the protective-agent bar and the image carrier while rotating such that the protective agent adheres thereto and is supplied to the image carrier in an irregular form.
