Description
Technical field
The present invention relates to printing consumables technical fields, more particularly, to a kind of carbon dust for being releasably attached to imaging device
Box.
Background technique
The imaging device of electro photography such as laser printer etc. is a kind of using electrofax principle, through overcharge, exposure
Light develops, and transfers, fixing, and the processes such as cleaning form the equipment of image on image forming medium such as paper.Imaging device is logical
It is often used the cartridge being removably installed in it and carbon dust is provided.And cartridge is other than accommodating carbon dust, it is usually also integrated
There are the developing members such as developer roll, powder feeding roller, powder outlet cutter, wherein powder feeding roller forms carbon dust layer for conveying carbon dust to developer roll, out
Powder knife is used to adjust the thickness of carbon dust layer on developer roll, and developer roll is then using on the carbon dust development photosensitive element carried thereon
Electrostatic latent image.In developing process, developer roll, powder feeding roller etc. generally require energization, so that required charge on carbon dust band.Each development
Component is electrically connected with each conductive contact that cartridge conducting end is arranged in respectively, is installed in cartridge to imaging device, is respectively led
Electric contact is connect with each output electric contact in imaging device respectively, to receive different voltage out of imaging device.
It is the cartridge that one kind disclosed in the prior art can be removably mounted on imaging device referring to Fig. 1, Fig. 1
Structure chart.Cartridge 1 includes box body 14, powder feeding roller (not indicating), developer roll 11, powder feeding electrode 13 and development electrode 12, development
Electrode 12 and powder feeding electrode 13 are protruding with respect to box body 14, i.e., development electrode 12 includes development protrusion 121, and powder feeding electrode 13 wraps
Protrusion containing powder feeding 131, powder feeding protrusion 131 and development protrusion 121 are protruding with respect to box body 14, so as to the developer roll of imaging device
Power supply contact 2 is contacted with development protrusion 121, and the powder feeding roller power supply contact 3 of imaging device is contacted with powder feeding protrusion 131, by sending
Powder protrusion 131 and development protrusion 121 are that powder feeding electrode 13 and development electrode 12 are powered, so as to development electrode 12 and powder feeding electrode 13
Apply developing bias and powder feeding is biased on the developer roll 11 and powder feeding roller of cartridge 1, to make the carbon dust of developing location aobvious
Between shadow roller 11 and powder feeding roller under the influence of potential difference, realize carbon dust from powder feeding roller to developer roll 11 transfer.Simultaneously in developer roll
11 and other component electric field forces effect under to photosensitive drums powder supply, thus to photosensitive drums develop, then by transfer carbon dust turn
It prints on paper.
Development electrode 12 and powder feeding electrode 13 are the moulding containing conductive material, and the conductive material in moulding point
Cloth is difficult to be uniformly distributed, and is electrically connected with imaging device unstable so as to cause the conducting end of cartridge 1, causes conductive bad, lead
Cause the voltage differences between developer roll 11 and powder feeding roller seldom, and then the carbon dust influenced in powder feeding roller is transferred on developer roll 11.
The carbon dust being transferred on developer roll 11 is few, will further influence developer roll 11 to photosensitive drums powder supply, bad so as to cause printing
Phenomenon.Meanwhile conductive material is added in moulding, this high molecular material cost is very high, substantially increase cartridge 1 at
This.
