ABSTRACT:
A toner container is shown which includes a toner brush that moves toner to a rectangular opening partially closed by flexible triangular masks for restricting the flow of toner into contact with a sheet of paper to cause the toner to diverge as it flows across the paper thus preventing the toner from passing under the edge of the paper. The toner brush is rotatably mounted in the rectangular opening within a nonmagnetic cylinder which may be intermittently rotated. A scraper mounts against the nonmagnetic cylinder for removing accumulated toner therefrom during the intermittent rotation. As the toner moves around the cylindrical shell, under the urging of the toner brush, it is passed through a portion of the container that is laterally constricted to urge the toner into a narrow configuration in preparation for presentation to the masked opening.
