  • Publication number: 20030156868
    Abstract: A photosensitive drum cleaning device of a wet type printer includes: a cleaning blade disposed on a photosensitive drum to contact and wipe an outer circumference of the rotating photosensitive drum, for removing a developer that has not been transferred to a transfer belt but remains on the photosensitive drum; and a developer drain holder for collecting and discharging the developer removed by the cleaning blade. The cleaning blade includes first and second guide wings which are respectively formed at opposite sides of a contact portion of the cleaning blade and the photosensitive drum and which have a predetermined height. The guide wings prevent the developer that is wiped by the cleaning blade from streaming down over the opposite sides of the cleaning blade. The guide wings are formed integrally with the cleaning blade to have a width that is thinner than the thickness of the cleaning blade.

  • Publication number: 20030044202
    Abstract: A liquid developer imaging system and a method using the system for developing an image, including a cartridge for containing a developing solution; a developing container for receiving the developing solution supplied from the cartridge via a predetermined supply line; a developing roller partly submerged in the developing solution contained in the developing container, installed to be rotated facing a photosensitive object; and a metering blade for scraping off the developing solution coated on the surface of the developing roller to a predetermined thickness, is provided. According to the system, a developing supply structure can be considerably simplified because a high-density developing solution is directly used in developing an image without a process of diluting the solution, and an image can be developed to have high definition because the concentration of the developing solution coated on the developing roller is regularly controlled by a metering blade.

  • Patent number: 6370347
    Abstract: A squeezing apparatus of a liquid electrophotographic color printer for removing carrier of a developer from the developer without causing any damage to an image developed on a photosensitive medium. The squeezing apparatus includes a dual-structure squeezing roll that has a squeezing roll section of a low peel force for squeezing out and removing the carrier from the developer applied to the image area of the photosensitive medium, by its passive-rotational movement while being forced against the image area of the photosensitive medium by a certain force. The squeezing apparatus also includes a pair of friction roll sections, each friction roll section disposed at an end of the squeezing roll section with a gap to oppose each other at a certain interval, the friction roll sections having a high dry-friction coefficient and are passive-rotated while being forced into tight contact with the non-image area of the photosensitive medium by a certain force.
