Abstract

PURPOSE: To make a blank part at the end of copy and facilitate separation of copying paper from photoreceptor, by applying a transfer voltage between the copying paper and photoreceptor by means of a transfer changer of which opening part is narrowed from the bottom part.
CONSTITUTION: The toner image of a photoreceptor 1 is transferred on a copying paper 6 under the voltage applied by a transfer charger 5. At this time, when a voltage is not applied to a transfer charger 5a, a blank part may be formed in the area of about 20mm at the end of copying paper 6, but the boundary is not sharp. By narrowing the width W of opening part of the transfer charger 5b, a sharp boundary may be obtained, so that a sharp blank end may be formed when transferring a positive image on a positive image or transferring a negative image on a positive image. Therefore, the trouble of difficutly in separation due to attraction of copying paper to the photoreceptor due to electrostatic force may be solvend.
