Abstract

PURPOSE: To make possible the formation of an even developer layer of a desired thickness of a developer support by disposing the magnetic member to be disposed in opposition to the main pole of a stationary magnet in the specific position.
CONSTITUTION: There is a main pole 2 in a stationary magnet roll 1 and a non- magnetic sleeve 3 is disposed on the outer side. A blade 4 of magnetic material is provided in opposition to the main pole 2 and plays the role of coating the insulation-type magnetic toner 5 being supplied from a case 6 along with the revolution of the sleeve 3 to an adequate thickness on the sleeve 3. Moving the blade 4 within the range of θ≤l in the rotating direction of the sleeve 3 and in a range smaller than this in the opposite direction where the magnetic pole width of the main pole 2 is let 2l makes possible controlling the thickness of the toner.
