ABSTRACT:
An image bearing structure includes an image drum including at least one slot, a plurality of ring electrodes formed on an outer circumference of the image drum, and a control board positioned within the slot of the image drum, and connected to the plurality of ring electrodes, to detect a defect of the ring electrodes. As a result, the image bearing structure detects a defect within a short time and without requiring a separate detecting device.
