Abstract (en)
[origin: EP0033647A2] A cleaning device for a transfer type electrostatic copying apparatus which comprises magnetic brush cleaning means for cleaning off a magnetizable toner remaining on a photo sensitive material after transfer, comprising : (a) a hair brush roller disposed between the magnetic brush cleaning means and a transfer zone, and having a construction that a hair brush is filled on a peripheral surface of a cylindrical sleeve of light transmitting material and driven for rotation and is contact with the photosensitive material; and (b) a charge eraser lamp secured within the cylindrical sleeve. The photosensitive material or photoreceptor is almost completely erased with respect to the charge, and consequently, the cleaning efficiency is markedly improved owing to the facilitated removal of the developing material through by the magnetic brush.
