Zusammenfassung:A toner feeder is provided for use with a magnetic roller to tone electrostatic images. The feeder includes a doctor blade attached to an adjustable block for varying the gap between an edge of the blade and the magnetic roller. The block and blade combine to define a recess above the blade and toner builds up in the recess to present a living wall of toner. This reduces agglomeration and build up of toner lumps. The invention is particularly useful with toners requiring relatively low fusing pressures.
