A method of fabricating an image forming element, the method comprising:
- preparing an image drum;
- transferring conductive ink as a pre-form of a plurality of ring electrodes on an outer circumference of the image drum using an imprinting process;
- solidifying the conductive ink on the outer circumference of the image drum to form the plurality of ring electrodes;
- and
- forming an outer insulating layer on the outer circumference of the image drum having the plurality of ring electrodes.
A method of fabricating an image forming element, the method comprising:
- preparing an image drum having a first surface energy;
- coating a conductive ink over an entire part of an outer circumference of the image drum;
- preparing a cylindrical mold having a plurality of convex patterns formed at a pitch corresponding to that of a plurality of ring electrodes to be later formed on the image drum, the cylindrical mold having a second surface energy greater than the first surface energy of the image drum;
- placing the cylindrical mold and the image drum to a proximity to each other, and rotating the cylindrical mold and the image drum with respect to each other so that the coating of the conductive ink is partially removed from the image drum;
- solidifying the remaining conductive ink on the image drum to form the plurality of ring electrodes;
- and
- coating an outer insulating layer on the outer circumference of the image drum on which the plurality of ring electrodes are completely formed.
An image forming element fabricated according a method which includes preparing an image drum, transferring conductive ink as a pre-form of a plurality of ring electrodes on an outer circumference of the image drum using an imprinting process, solidifying the conductive ink on the outer circumference of the image drum to form the ring electrode, and forming an outer insulating layer on the outer circumference of the image drum having the plurality of ring electrodes.
An imprinting system comprising:
- a drum holder to rotatably support an image drum;
- an ink roller to rotate, which one portion thereof is submerged in conductive ink held in an ink reservoir;
- and
- a cylindrical mold to rotate relatively between the ink roller and the image drum, the cylindrical mold having a plurality of convex patterns formed at a pitch to correspond to that of a plurality of ring electrodes to be later formed on the image drum so that the conductive ink on the surface of the ink roller is transferred onto the image drum via the convex patterns.
An imprinting system comprising:
- a drum holder to rotatably support an image drum;
- a plate type mold movable in relation to the image drum, and having a plurality of convex patterns formed at a pitch to correspond to that of a plurality of ring electrodes to be later formed on the image drum;
- and
- an ink roller to supply conductive ink onto the convex patterns of the plate type mold, wherein the conductive ink is transferred from the convex patterns of the plate type mold onto the image drum.
An imprinting system comprising:
- a drum holder to support an image drum;
- an ink roller to rotate, a portion of the ink roller is submerged in conductive ink held in an ink reservoir;
- and
- a cylindrical mold to rotate between the ink roller and the image drum, the cylindrical mold having a plurality of protrusions formed at a pitch to correspond to that of a plurality of ring electrodes to be later formed on the image drum so that the conductive ink on the surface of the ink roller is transferred onto the image drum via the plurality of protrusions.
