Abstract

Disclosed is a copying apparatus which comprises a rotatable photoconductive drum, a charger unit for charging the drum, an exposure unit for exposing the charged drum in accordance with a document pattern, a developer unit for developing a latent image obtained by the exposure as a toner image, a transfer unit for transferring the toner image to paper, and a cleaning unit for removing toner remaining on the photoconductive drum after the transfer. The cleaning unit brings its cleaning blade into contact with the drum to scrape off the toner from the drum. The photoconductive drum is rotated at a speed considerably lower than the rotating speed for a copying mode after completion of a copying cycle, and is stopped after the passage of a predetermined time. When the drum is stopped, the cleaning blade is separated from the drum.
