Abstract

An image forming apparatus includes a photosensitive member, a charging device for charging the surface of the photosensitive member at a constant potential, a light beam for exposing the photosensitive member charged by the charging device to form an electrostatic latent image, a developing device for developing the electrostatic latent image by selectively sticking toner to the surface of the photosensitive member so as to correspond to the electrostatic latent image formed by the light beam, and a transfer device for transferring to recording paper the toner image formed by the developing device on the surface of the photosensitive member. The image forming apparatus is applied to a cleanerless system in which the developing device develops the toner image and simultaneously sucks and recovers residual toner remaining on the surface of the photosensitive member after transfer. The image forming apparatus further includes a scraping device that is pressed against the surface of the photosensitive member and scrapes the surface of the photosensitive member, while allowing the residual toner to pass through.
