IMAGE DRUM AND METHOD FOR MANUFACTURING THE IMAGE DRUM

摘要

An image drum and a method for manufacturing the image drum are provided to form connecting parts for connecting ring electrodes with a terminal of a control chip without using laser precision machining to reduce the manufacturing cost and improve productivity. A cylindrical drum body(110) is prepared. A PCB(Printed Circuit Board)(300) including a control chip for applying a voltage to an image drum and a terminal connected to the control chip is bonded to the inside of the drum body in such a manner that the terminal is exposed to the outside of the drum body. A sacrificial structure is formed on the terminal. A region of the PCB other than the sacrificial structure is coated with an insulating material. The sacrificial structure is removed to form connecting holes. The connecting holes are filled with a conductive material. A plurality of ring electrodes is formed in parallel on the drum body and the exposed portion of the PCB in such a manner that the ring electrodes come into contact with the conductive material.
