Abstract
An image forming element includes an image drum including a plurality of ring electrodes and a slot. The plurality of ring electrodes are formed to be spaced apart from one another on a circumference of the image drum. The slot is formed in a longitudinal direction on the image drum. A connecting member includes a plurality of connecting electrodes and is disposed inside the image drum so that an end of the connecting member is received in the slot. The connecting electrodes are electrically connected with the ring electrodes one to one on the same line.
Claims32
An image forming element comprising:
- an image drum comprising a plurality of ring electrodes and a slot, wherein the plurality of ring electrodes are formed to be spaced apart from one another on a circumference of the image drum and the slot is formed in a longitudinal direction on the image drum;
- and
- a connecting member comprising a plurality of connecting electrodes and arranged inside the image drum with each of the plurality of connecting electrodes protruding into the slot and electrically connecting with the ring electrodes one to one on the same line,
- wherein the connecting member is formed of a flexible material, and
- wherein the connecting member is wound inside the image drum.
An image forming element comprising:
- an image drum comprising a plurality of ring electrodes and a slot, wherein the plurality of ring electrodes are formed to be spaced apart from one another on a circumference of the image drum and the slot is formed in a longitudinal direction on the image drum;
- and
- a flexible printed circuit board (FPCB) comprising a plurality of connecting electrodes of fine patterns and disposed inside the image drum with each of the plurality of connecting electrodes protruding into the slot and electrically connecting with the ring electrodes one to one on the same line,
- wherein the FPCB is wound inside the image drum.
A method of manufacturing an image forming element, the method comprising:
- providing an image drum and a connecting member, wherein the image drum comprises a slot formed in a longitudinal direction and the connecting member comprises a plurality of connecting electrodes spaced apart from one another on the same plane and electrically insulated from one another;
- disposing the connecting member inside the image drum so that each connecting electrode protrudes into the slot and is externally exposed from the image drum;
- and
- forming a plurality of ring electrodes on a circumference of the image drum to correspond to the respective connecting electrodes one to one and electrically connect with the connecting electrodes,
- wherein the connecting member is formed of a flexible material, and
- wherein the connecting member is disposed inside the image drum in a winding state.
