Abstract
PURPOSE: To form a thin toner magnetic brush of uniform thickness and density in a simple constitution, by setting the spacing between the magnetic doctor to define the thickness of developer in the magnetic field and the developing member supporting means smaller than the spacing between the developing member supporting means and the latent image holding means.
CONSTITUTION: By means of a magnetic doctor 10 provided in the magnetic field in which a fixed magnet roll 9 is formed, a magnetic brush formed with a thin, uniform density toner layer is formed on the developing member supporting means such as nonmagnetic rotating sleeve 8 as the slipping of toner by curtain of brush-shaped toner is being restricted. The spacing P between the doctor 10 and sleeve 8 is set smaller than the spacing q between the sleeve 8 and photosensitive drum 1 of latent image holding means, so that the latent image may be developed and processed excellently by means of a thin magnetic brush of uniform thickness and density in a simple constitution, regardless of effects of toner aggregation or accumulation of paper chips.
