Abstract
PURPOSE: To perform the separation of copying paper from photoresecptor readily and surely by making use of charging of copying paper owing to transfer electric field.
CONSTITUTION: A grounded conductive roller 11 is disposed in proximity to a charger 4 and is made contactable to the back of copying paper 1. Then, after the copying paper 1 makes contact to the surface of the photoreceptor 2a of a photosensitive drum 2 and is transferred to toner by the transfer electric field owing to corona discharging from a charger 4, it is strongly attracted to the conductive roller 11 side and detaches from the photosensitive drum 2 by bending its course along its surface and is advanced in the arrow d direction because the equivalent concentration point of the charges having been charged has offset to the conductive roller 11 side. Hence, the copying paper 1 is readily and surely separated from the photosensitive drum 2 without giving adverse influence to the copy images.
