Abstract
An electrostatic copier wherein an electrostatic image pattern is formed in the photoconductive surface of a rotatable endless carrier, toner particles are attracted to the patterns to form a visible image and thereupon transferred to an image carrier and a cleaning web contacts a portion of the photoconductive surface to clean it in preparation for the formation of another image pattern, a brush roller has an axis of rotation extending parallel to the axis of rotation of the endless carrier, the brush roller engaging the surface upstream of the portion as considered in the direction of rotation of the endless carrier and being rotated exclusively by frictional contact with the surface so as to remove from the surface carrier particles adhering thereto and prevent them from reaching the web.
