Patent ID: 8366944

Claim:
A method of fabricating an image drum, the method comprising: preparing a hollow drum body having a slot extending in a longitudinal direction; preparing a printed circuit board (PCB) comprising board terminals; mounting the PCB inside the hollow drum body with a fixing member such that the board terminals of the PCB are placed in the slot of the hollow drum body; coating a first insulating layer on an outer circumference of the hollow drum body; forming non-continuous ring electrodes on the first insulating layer corresponding to the board terminals of the PCB, the non-continuous ring electrodes each having ends disposed adjacent to a corresponding one of the board terminals and on opposite sides of the slot; exposing the board terminals between the ends of the non-continuous ring electrodes by etching the first insulating layer using the non-continuous ring electrodes as an etching mask; and forming connecting electrodes to electrically connect the board terminals to the corresponding non-continuous ring electrodes.
