The doctor blade arrangement described in the specification includes a doctor blade made of resilient sheet material having a toner thickness control end lightly engaging a toner layer on the surface of a development roller to control the thickness of the toner layer and a mounting end which is bent to be resiliently received in a mounting groove of the electrophotographic apparatus in which doctor blade is used. In one embodiment the mounting end has parallel bends forming a U-shape leading to a projecting mounting lip which is engaged by a projecting hook portion at one edge of the mounting groove. In other embodiments the mounting lip extends toward or away from the plane of the toner thickness control end of the doctor blade.
