<p>PROBLEM TO BE SOLVED: To provide the developer feeding device for a wet type electrophotographic system printing unit whose structure is improved, so as possible to adequately adjust a density of the developer and a level of liquid position. SOLUTION: This device is allowed to incorporate the developer storing tank 40 storing the developer mixed with liquid carrier and ink, the carrier cartridge 10 feeding the liquid carrier to the developer tank 40 through the carrier feeding route 11, the ink cartridge 20 feeding the ink through the ink feeding route 21 to the developer storing tank 40, a developing unit 30 developing an electrostatic latent image being fed the developer from the developer storage tank 40 through the developer feeding route 34, and the processing tank 50 in which the developer stored in the developer storing tank 40 through the developer discharging route is discharged/stored. In such a manner, the density of developer and the level of liquid position adjustment in the developer storage tank 40 are facilitated by making the developer in the developer storage tank 40 discharged in providing the additional tank. Moreover, the developer in the processing tank 50 can be recycled being free from the density deviation. Further more, at the ink cartridge replacing time, the developer of low quality or incorporating impurities can be simultaneously wasted.</p> |
