摘要： An ink delivery system of a liquid electrophotographic color printer which supplies liquid developers of predetermined concentration, each of which is a mixture of a toner and a liquid carrier, to a plurality of respective developing units, and which recovers the carrier using a drying/condensing unit which absorbs and evaporates the carrier remaining on the photosensitive medium after development. A plurality of circulation tanks store respective developers to be supplied to a corresponding developing unit. Respective concentration measuring devices measure the concentration of the developers. A waste tank receives waste developer produced in the plurality of circulation tanks, and includes a waste developer agitating device for agitating the waste developer. A plurality of ink storage tanks store concentrated inks of predetermined colors to be supplied to the respective circulation tanks, and include respective ink agitators driven by a single driving source. A carrier storage tank stores a carrier to be supplied to the circulation tanks, and having an inclined surface at the bottom so that water and a liquid carrier condensed by the drying/condensing unit can be stored in a stratified state. A refill cartridge stores a concentrated ink or carrier with compressed air and is removably installed at a common installation portion provided at the main body of the printer. A developer refilling/waste recovering mechanism refills a concentrated ink or carrier of the refill cartridge into a corresponding ink storage tank or carrier storage tank and recovers the waste developer stored in the waste tank to an empty refill cartridge.

摘要： A developing solution feeder of a wet type electrophotographic color printer includes a plurality of circulation tanks for storing the developing solution to be fed to a developing unit; a plurality of injection nozzles for jetting the developing solution stored in the circulation tanks to a developing gap of the developing unit; a plurality of ink storage tanks and a carrier storage tank for respectively storing the condensed ink of a certain color and a carrier to be fed to the circulation tanks, respectively; a waste tank for collecting the waste developing solution produced from the circulation tanks; a refill cartridge for the supplementation of the condensed ink or the carrier; developing solution refilling/waste developing solution collecting means for refilling the ink storage tanks or the carrier storage tank with the condensed ink or the carrier, respectively, and for evacuating the waste developing solution collected in the waste tank to the empty refill cartridge; and ink injecting/constant feeding means having a gear pump for jetting the condensed ink or the refill cartridge to the ink storage tanks during the condensed ink refilling process by the pumping action while being driven in a certain direction, and for feeding the appropriate amount of the condensed ink stored in the ink storage tanks to the circulation tanks while being driven in a reverse direction. Accordingly, since the condensed ink within the refill cartridge is jetted to the ink storage tanks by the gear pump, the condensed ink is stored in the refill cartridge, purely. As a result, the property change of the condensed ink, which is caused due to the presence of compressed air, is prevented. Further, since the gear pump functions to feed the condensed ink of the ink storage tanks to the circulation tanks, the condensed ink is fed to the circulation tanks in more appropriate amounts.

摘要： A housing assembly of an OPC unit to protect an OPC drum in an image forming apparatus includes a main housing enclosing at least a half of a large-diameter OPC drum and provided with a main-opening selectively contacting a plurality of developing units and a plurality of sub-openings, a first housing and a second housing each mounted on a side of the main housing, a handle hingedly connected to the main housing, and a plurality of brackets mounted on opposite sides of the main housing. As a result, the housing assembly of the OPC unit allows easy development, electrification, exposure, image transfer and treatment of a waste toner, and reliability of the image developing process increases due to the fixation of the developing units. Also, since the exposure of the OPC drum is minimized, an area of the OPC drum to be contaminated can be reduced.
