Abstract
PURPOSE: To form the even developer layer of a desired thickness by opposedly disposing a developer thickness defining means to a developer support.
CONSTITUTION: A doctor blade 4 composed of magnet is opposedly disposed by leaving a desired spacing to a magnetic material developer support 2. Then, if the portion between the doctor blade 4 and the magnetic pole of the magnetic material developer support 2 induced by its magnetic force is in a magnetic field, a magnetic torner 3 continuing in yarn form along the magnetic lines of force becomes continuous just like a curtain along the magnetic lines of force in this gap, whereby the going through of the excess toner between the mangetic material developer support 2 and the doctor blade 4 is prevented and the magnetic toner 3 layer of a desired thickness is evenly formed on the magnetic material developer support 2.
