Problems solved by technology
[0003] However, in the conventional developing solution supply system, since the agitator is separately installed in each of the ink cartridge and the mixing tank, the number of components constituting the system is large, and thus the system structure is complicated.
Especially, when a conventional developing solution supply system uses inks of multiple colors in a color laser printer, a plurality of agitators twice the number of colors are used, making the device complicated.

Embodiment Construction
[0010] Referring to FIG. 1, a developing solution supply system according to a first embodiment of the present invention includes: an ink cartridge 10 filled with ink 1 of a predetermined color; a carrier storage tank 20 filled with a liquid carrier C. A mixing tank 30, which is installed in contact with the ink cartridge 10 with a partition 60 therebetween, stores a developing solution T obtained by mixing the ink 1 in the ink cartridge 10 and the carrier C in the carrier storage tank 20 at a certain ratio. One stirrer stirs the ink 1 and the solution T stored in the ink cartridge 10 and the mixing tank 30, respectively. The agitator includes: first agitating blades 31 and 33, which are rotatably installed in the mixing tank 30; second agitating blades 11, opposite to the first agitating blades 31 and 33, rotatably installed in the cartridge; and The partition plate 60 between the second stirring blade 11 and the first stirring blades 31 and 33 . The first and second stirrin...

A developing solution supplying system for a wet type developer includes an ink cartridge for storing ink; a carrier storage tank for storing liquid carrier; a mixing tank located adjacent to the ink cartridge having a bulkhead therebetween for storing a developing solution; a first agitating blade rotatably installed in the mixing tank; a second agitating blade rotatably installed in the ink cartridge opposite the first agitating blade; and an actuator separated from the first and second agitating blades, for imparting interlocking rotation to the first and second agitating blades. Owing to this structure, the solutions in the ink cartridge and the mixing tank can be simultaneously agitated by a single driving source. The structure of the developer is simplified.
Description
technical field [0001] The invention relates to a developing solution supply system for a wet developing device, in particular to a developing solution supply system for a wet developing device with an improved agitator, so that the solution maintains a uniform concentration distribution. Background technique [0002] A wet developer develops a latent image by supplying a developing solution to a photosensitive medium on which an electrostatic latent image is formed, such as a photosensitive tape. The wet developer includes a developing device that supplies a developing solution to a photosensitive medium and a developing solution supply system that continuously supplies the developing device with a concentration within a predetermined range. The developer solution is a solution made by mixing an undiluted ink solution containing about 9-10 wt% powder toner by weight with a liquid carrier such that the developer solution has a toner concentration of 3-5 wt%. The developing ...
