ABSTRACT:
A copying apparatus has a rotatable medium, processing apparatus including a charger for forming an image of an original on the rotatable medium and for transferring the image to a transfer material, a residual charge remover, a copy setting mechanism and a start switch. The rotatable medium is rotated during the copying operation with both the charger and residual charge remover operating and is post rotated after the copying operation with the charger disabled but the residual charge remover operating. When the start switch is operated during the post-rotation but before the charger becomes disabled, the charger remains operative and copying is restarted.
