ABSTRACT:
A cleaning method is provided for electrostatic copying apparatus of the transfer type in which a polarizable magnetic toner is used as a developer to remove residual toner from the surface of a photoconductive member after the transfer of toner images. The method comprises the steps of charging the toner remaining on the surface of the photoconductive member to the same polarity as the charge for sensitizing the surface of the photoconductive member after the transfer of a toner image, uniformly exposing the photoconductive surface simultaneously with or after the charging step, and thereafter removing the residual toner from the photoconductive surface by magnetic attraction.
