Abstract

PURPOSE: To obtain sufficient cleaning effect, recover the residual toner leaking by being swept off and obtain always sharp images by removing the toner remaining on a photosensitive surface in two stages by a developing and cleaning device and a rotary bristle brush.
CONSTITUTION: After normal images are formed on transfer paper A, the transfer paper A is stripped by a stripper 24, is guided by a transfer-out path 28 and is transferred out onto a tray 27. And it turns out that on this way it is destaticized and fixed by a destaticizer 29 and a fixing device 30. During this time, a photosensitive drum 4 undergoes the operation of the second turn and the erasing of residual change is accomplished for the images remained on its photosensitive surface 4a. Thence, the residual toner of the photosensitive surface 4a contacts the magnetic brush formed by a magnetic roller 20 and is thereby attracted to the magnetic brush side. Next, the residual toner which was not attracted to the magnetic brush side is swept off by a rotary bristle brush 22 and is captured and recovered by a developing and cleaning device 17.
